AITA for sending away my brother-in-law & his family because he wouldn't let my miracle baby hold his newborn baby

I (28M) am a former US Army soldier. Last 6 years, I was stationed in the Middle East. 3 years ago, I got shot and almost died. My heart stopped and they had to pull me out of there fast. I spent 3 months in the hospital. The last year they kept telling me I'd never be able to come home because the latest tests showed permanent damage. My wife had been with me the whole time, and she refused to leave. The Army decided that they could not keep me and that I was to be sent back to the States where I would be honourably discharged.<br><br>My wife and I came home a year ago. Last year, we found out that my wife was pregnant. The doctor told us that the baby should not have survived because of the damage my heart sustained, but somehow he did. Last week, I finally got to hold my newborn baby in my arms. My wife and I decided to name him Morgan. <br><br>The day he was born, my brother-in-law and his wife came to the hospital and visited. They have a 2-month-old baby girl. While they were there, I asked my brother-in-law if I could have Morgan hold his baby. My bro-in-law has been a dad for 2 months. I have been waiting to be a dad for 6 years. I want my son to be a good big brother. So I wanted to introduce them as early as possible because I think babies retain memories better than we think. My bro-in-law was like "Uh, I don't think that's a good idea" and his wife kept looking at him like she wanted to say something but didn't dare. I told him "It's fine, my son will be careful". He repeated his no. So I said "Listen, I've been waiting to be a dad for 6 years. The least you can do is let my newborn baby hold your baby". My bro-in-law looked at me like I went crazy and said "No. Your baby is not gonna touch mine". He grabbed his family and left.<br><br>My wife went ballistic the second they left. She called to ask him wtf was up with his behaviour and he said I was the one being crazy and disrespectful towards him. He said that we can't see them again until we're ready to apologise.<br><br>My wife told my mother about it and my mother said it was wrong of me to ask them to let a newborn hold a baby. I told her I wasn't asking. I was telling them. I'm the father and I get to make decisions for my son. She started yelling at me saying she raised me better. I said she didn't raise me because she was a poor mother and doesn't know the first thing about parenting.<br><br>I told my wife we're not going to be apologising.
