I’m sorry you are going thru such a hard time. You can’t predict the health of the baby from your previous binges but you can definitely do more harm by continuing, and I know you know that. When I was pregnant six years ago, I was worried sick I had harmed my baby because I drank heavily until I found out I was pregnant at 6 weeks. I stopped immediately after finding out. There was one day though I was so super stressed I drank one beer in my second trimester. The guilt from the one drink saved me from drinking anymore after that. Please continue to go to AA, even if just once a week and find online meetings as well. Reading “quit lit” might help you too.
After my baby was born, I slowly started back up and eventually was back to binge drinking daily. And raising a baby/toddler like that is mentally exhausting. I hope you can find a way to quit for good so you don’t have to go through the pain I did trying to quit with a young child.
