I have a 7 month old son. I'm 24 years old. Me and the girl started going out about 4 months into her pregnancy. I wanted to give it a shot and it didn't work out in the end (just split up). My advice is to not fool yourself. It's going to take all you have, so be ready to sacrifice your startup, social life etc. There will be time later for that. Just go at the same speed as the girl does, going from maternity and babycaring to getting a babysitter and going out.

My second advice is to give it a shot.
