I don’t know what your state will or won’t do about probation-but it sounds like he has been drinking and driving with your child on multiple occasions, and that is terrifying. Especially if his driving has been erratic / fast / dangerous enough to be pulled over more than once?
I would suggest contacting a lawyer-plus checking with the local police to see if he has indeed been stopped. It is scary to rock the boat, but getting the legal things in place has to be done at some point anyway.
