Breaking the news to baby daddy

Sophie

My husband and I have been trying for a while and we finally did it! I’m due May 7th!!! Hubby’s birthday happens to be the beginning of September so I’d really like to give him the best birthday present he’s ever gotten. He’s a botanist and I found a onesie that says small seeds become mighty trees, I figured I’d wrap it and give it to him for his birthday. I’m going crazy keeping the secret for the time being though. How did everyone else break the news to their baby daddy?
