That's awesome!
My wife and I have 4 kids total -
20 year old boy and girl twins (hers)
18 year old daughter (mine)
16 year old daughter (hers)
We met when the twins were like 5 and the youngest was almost 2. She didn't know who the twins dad was (one night stand) but the youngest dad is part of the family. (Good guy, we get along really well) So I raised them most of their life and the twins have always called me Dad.
I didn't know about my daughter until she was 2 even though Mom knew she was mine , just made a bad choice even though we split on good terms and I was a good guy, didn't do anything to warrant that.
SO, I missed ALL the baby time and this is exciting AF for me. Finally getting that opportunity that I missed so I make the most out of every second I can get with the little guy.
I'm also a dumbass when it comes to babies

I'm learning all this stuff for the first time and, there's some things that I would have never have though about lol
Like putting pillows near the baby when they're asleep is a big no no apparently. Making sure blankets can't get over their heads. Babies can't have water until they're like 6 months old? (that's fucking crazy to me)
Plus, they've got all these monitors on him when he sleeps so they can see his heart rate and temperature and breathing and so on...... It just seems like overkill but, again, I'm baby dumb.
