Welcome to the forum. Your baby falling should be a huge wake up call. Imagine if he died or was paralyzed because of your condition. You would have the rest of your life to reflect on how alcohol ruined your childs life.
I assume you guys were driving drunk as well? Sounds like the police were doing a good job in removing your child from you.
I hope you visit here often. This site, along with AA and perhaps some counseling, could make a difference. Good luck! I will be pulling for you.
