When should you congratulate a colleague on a new baby?

Only after the news has been shared by the parents themselves — many wait until mother and baby are home. Once it is announced, reply the same day.

What if you barely know the colleague?

Two neutral lines are plenty: congratulations plus wishes of health. Joining the team collection counts as a message in itself.

What should you avoid writing?

Birth details, questions about weight, jokes about sleepless nights, hints about a second child, and questions about when the mother returns to work.

Congratulating a Colleague on a New Baby: 25 Messages

Formal, warm and light wording for the team chat — plus the lines that make everyone uncomfortable.

Published: August 11, 2026

A congratulation is not the same thing as a collection. This page is about the words; the money side lives in a separate guide.

Short answer: wait until the parents announce it, reply the same day, keep it about the family rather than the birth, and match the length to how close you actually are.
