They get scared.

Time. I've been with my man 4 years and he still was tweaky until he saw the ultrasound.

Definitely give him some time and space to soak it all in. Our wasn planned but my boyfriend didn't act like he was mad or upset at first. Just remember it's gunna be a lot of work. Our pregnancy wasn't planned we're 21 and 22 and he's a manager, good job and still isn't completely ready and I'm due in a month and a half. One thing you'll learn is the mom matures wayyyyy faster then the dad does. I'm still working with my boyfriend on some things he needs to change before the baby gets here. It's an interesting, fun, emotional process but it's all worth it in the end.

give him time. some guys are brats intill the baby is actually here

Give him time to soak it all in. I'm sure he will come around its still early just let him get use to the fact of a baby coming.

Mine was the same way when I told him , he didn't want a kid and now he's happy he's having a son he just needed time to realize there was nothing left to do

it will take time for him to digest it.

It depends on how you laid it to him too, but yea, let time do its thing ❤️

give him time let him soak it in. being a daddy is a lot of pressure too
