Someone on your team is about to go on maternity leave, and the team card is making its way around the office. Or the Slack thread just went up. Or you're staring at a blank email draft wondering how to say something that doesn't sound like it was generated by a corporate HR template. You want to be warm without being weird, personal without overstepping, and genuinely supportive without accidentally making it about the work they're leaving behind.
The reason maternity leave messages feel tricky is that they sit at the intersection of two things we're generally bad at combining: professional boundaries and genuine human emotion. This person is about to go through one of the most transformative experiences of their life, and your relationship with them exists primarily in a conference room. That's an awkward gap to bridge — but it's also an opportunity to show someone they matter to you as a person, not just as a colleague.
Here are 50+ messages organized by tone and situation. Find the category that matches your relationship, copy it, personalize if you want, and send it. Every message here is designed to be used exactly as written — or as a starting point you can adapt.
Warm & Heartfelt Messages
For coworkers you're genuinely close with — people you've shared lunches with, vented to after hard meetings, or consider real friends beyond the job title. These lean into emotion because the relationship supports it.
"I am so incredibly happy for you. You're about to meet the person you've been waiting for, and I know you're going to be the most amazing parent. Enjoy every single second of this leave — you deserve it completely."
"Watching you get ready for this has been one of the highlights of my year. You radiate joy when you talk about it, and that kid is going to be so lucky. Go be with your family — we'll hold things down here."
"This is your moment. Don't think about work, don't check Slack, don't worry about anything here. The only job that matters right now is the one you're about to start. I'm so happy for you."
"You've been such an incredible colleague and friend. I know you'll bring that same warmth, patience, and heart to parenthood. Congratulations — I'll miss you around here, but I'm so glad you get this time."
"The qualities that make you exceptional at work — your empathy, your calm under pressure, the way you make everyone around you feel seen — are going to make you a wonderful parent. Enjoy this beautiful chapter."
"I just want you to know that I'm genuinely, deeply happy for you. This is the big one. Go be present for it. And when you're ready to come back, I'll be here with coffee and zero judgment about how many baby photos you show me."
"You've given so much of yourself to this team. Now it's time to give all of that love to your family. Congratulations on this incredible milestone — you're going to be phenomenal."
Professional Messages
For managers you respect, colleagues you don't know deeply, or situations where you want to be warm but appropriately boundaried. These strike the balance between genuine and professional.
"Congratulations on this wonderful milestone. Wishing you and your family a smooth, joyful transition. Enjoy your leave — everything here will be well taken care of."
"What an exciting time for you and your family. Wishing you all the best as you begin this new chapter. We look forward to welcoming you back whenever you're ready."
"Congratulations! This is such a significant moment, and you deserve to enjoy every part of it. Wishing you a wonderful leave and a healthy, happy arrival."
"Wishing you the very best as you head into maternity leave. This is a once-in-a-lifetime experience, and I hope you get to be fully present for all of it. Congratulations."
"Congratulations on your growing family. Wishing you rest, joy, and all the good things that come with this next chapter. We'll be here when you return."
"Happy to see you stepping into this exciting new role — the most important one yet. Enjoy your time with your family, and don't give work a second thought."
Funny & Light-Hearted Messages
For colleagues who appreciate humor and would find a too-serious card awkward. These are warm underneath the jokes — never mean-spirited, never about their body, never implying they'll fail at parenting.
"Congratulations! You're about to trade pointless meetings for pointless 3 AM wake-ups. Somehow, the second one is more rewarding. Enjoy every exhausting, beautiful second of it."
"Just a heads up: you're about to discover that 'working under pressure with tight deadlines' was actually great training for parenthood. You've got this. Congratulations!"
"I fully expect you to come back with at least 400 baby photos and zero apologies. And I am here for every single one. Congratulations!"
"You're leaving us for someone who can't even hold a conversation yet. Honestly? Can't blame you. Congratulations — that's a serious upgrade."
"The good news: you're about to go on leave. The bad news: your new boss doesn't care about weekends, holidays, or your sleep schedule. Congratulations — it's the best job you'll ever have."
"Pro tip: when people ask 'how's the baby?' just answer the way you'd answer 'how's the project?' — 'making progress, timeline is fluid, stakeholder is demanding.' Congratulations!"
"You managed to survive [quarterly reviews / sprint planning / that one client]. Parenthood is going to be a breeze. Sort of. Congratulations!"
"I'm not saying I'm jealous of your leave, but I am saying I'd also like several weeks away from email. Congratulations on the much better reason for it."
Messages for a Team Card or Group Slack
Written in the collective voice for group cards, team emails, or channel-wide Slack messages. These should feel like the whole team is speaking, not just one person. If you're the one drafting the message for the team, these are ready to go.
"From all of us: congratulations on this incredible next chapter. You've made this team better in every way, and we're so happy for you. Enjoy your leave completely — we've got everything covered here."
"The whole team wants you to know: take your time, be present, and don't check Slack. This is a once-in-a-lifetime thing. Everything here will be waiting for you when you're ready. Congratulations from all of us!"
"We're so excited for you and your family. You bring so much energy, warmth, and talent to this team — and we know you'll bring the same to parenthood. Congratulations! We'll miss you and we'll be here when you get back."
"From everyone on the team: congratulations! Wishing you rest, joy, and a baby who cooperates with nap time. We're all rooting for your family. Come back whenever it feels right."
"This team is so happy for you. You've given us your best every day, and now it's time to give that love to your family. We've got things handled — go enjoy this beautiful moment. Congratulations!"
"On behalf of the whole team: congratulations! We're going to miss your [humor / calm / energy / expertise], but we're even more excited about what's ahead for you. Wishing your family a healthy, happy beginning."
Messages from a Manager to a Direct Report
If you manage someone going on leave, your message carries extra weight. It sets the tone for whether they feel genuinely supported or subtly pressured. The goal: make them feel celebrated, not anxious about stepping away. Never mention projects, coverage, or timelines.
"I want you to know how happy I am for you. You've earned every bit of this leave, and I want you to take it fully — no checking in, no worrying about the team. We'll be absolutely fine. Go be with your family."
"Congratulations on this amazing milestone. I've loved working with you, and I know you're going to bring the same thoughtfulness and care to parenthood that you bring to everything here. Enjoy every moment."
"You've been an incredible part of this team, and that's not going anywhere. Take all the time you need, come back when you're ready, and know that your role will be here for you. Congratulations — this is wonderful news."
"I mean this sincerely: do not think about work. Not even once. You've built something great here, and it's strong enough to run without you for a while. Go be fully present for your family. We'll celebrate again when you're back."
"As your manager, I want to be clear: your leave is yours. Take every day of it. There's nothing here that can't wait. As a human being, I'm just really happy for you. Congratulations."
"Congratulations! I'm so proud of the work you've done here, and I know this next chapter will be even more rewarding. The team is in good hands while you're away — go enjoy this time without a single reservation."
Short & Sweet Messages for Slack or Chat
When the group card is already full, when you're dropping a quick DM, or when the moment calls for brevity over poetry. These are one to two lines — genuine without being a wall of text.
"So happy for you. Enjoy every second of this — you deserve it."
"Congratulations! Wishing you and your family a beautiful beginning."
"You're going to be an incredible parent. Enjoy your leave!"
"Best wishes for your leave! Can't wait to hear all about it when you're back."
"Congrats! Go enjoy this — we've got things covered here."
"So excited for you. Take all the time you need — we'll be here."
"Congratulations! This is the good stuff. Enjoy it fully."
"Happy for you! Wishing your family health, rest, and joy."
Welcome Back Messages
For when they return from leave. The transition back is often harder than people expect — these messages should feel warm and pressure-free. Don't immediately ask about the baby's sleep schedule or dive into what they missed. Let them land.
"So glad to have you back! No rush on anything — take your time settling in. We missed you, and we're happy you're here."
"Welcome back! I hope your leave was everything you needed it to be. Just know there's zero pressure to hit the ground running — ease in at whatever pace feels right."
"It's great to see you again. Whenever you're ready to catch up, I'm here — but genuinely, take your time. The important thing is that you're back and we're glad."
"Welcome back! We held the fort and only set one small fire. Just kidding — everything's fine. Happy to have you here again."
"So happy to see you! I know coming back can feel like a lot — just know everyone here is supportive and there's no expectation to catch up on everything immediately. Welcome home."
"The team just got better. Welcome back! I hope your time with your family was wonderful. Let me know if there's anything I can do to make the transition easier."
"Welcome back! We missed your [perspective / humor / calm presence]. Take whatever time you need to ease back in — we're just glad you're here."
Tips for Writing a Great Maternity Leave Message
Whether you're writing a card, a Slack message, or a quick email, a few principles go a long way. The best maternity leave messages feel effortless — but they follow some simple rules.
Keep it about them, not about work
Resist the urge to mention projects, coverage plans, or how the team will manage. Your message should make them feel celebrated, not guilty about leaving. The logistics can happen in a separate conversation.
Don't ask about return dates
Even casually. "Can't wait to have you back in September!" puts a timeline on something that should feel open-ended. Let them set their own pace without feeling watched.
Skip the assumptions
Don't assume they'll breastfeed, stay home longer than planned, or come back part-time. Don't comment on their body, energy level, or how "ready" they look. Keep the focus on congratulations and support.
Be inclusive with language
If your company uses "parental leave," mirror that. If the person refers to their own leave as "maternity leave," follow their lead. When in doubt, "parental leave" works universally and respects all family structures.
Personal beats generic
Even one specific detail — "I know how excited you've been about this" or "your calm energy is going to make you a great parent" — transforms a generic card into something memorable.
Match the medium
A handwritten card can be three sentences and feel meaningful. A Slack DM should be quick. A team email can be a full paragraph. Let the format guide the length — don't write a novel in a chat message.
