Hello!
Me personally i don't have kids, i like to think im still "young" i think (24). But for me my nephew was a game changer. Making me actively think "Maybe i should stick around and stop drinking so he has an uncle". I am with you, in the respect that family is just everything, My final say is this, if you can't personally say your child will be safe without you here, why drink more? get off the bottle for them, not you for them. I wish you the best.
