Husband staring to freak out- anyone else?!!

Mary Beth
It's 4am and I'm wide awake, I decided to look at my husbands phone. I opened his texts and saw one to his mom, it said he was freaking out about becoming a dad. It said, "I can do this, right?" He asked if he was going to be a good dad. I don't know what to do. I don't know if I should talk to him about it or let him come to me. This is our first and he's due in 4 weeks. My husband had a weird/hard childhood and everyone has walked out on him at one point or another (except me). He's determined to give our child a different a life, and I know he will be an amazing dad. Is this just a freak out a lot of men go through?
