Its a rare circumstance that a newborn is allowed away from the mother while breast feeding. Even if you're not (I urge you to do so) most infants stay with their mother for several years.

I totally understand your desire to protect your child, and your assessment that he is not a good parent in his current state. One thing you will find, is that the child will need and want contact with the father, no matter how bad he is. You need to determine if there is any danger to the child and mitigate that by having supervised visits or whatever, but it is best not to cut off contact altogether. It kind pf leaves a hole in the child's life to do that and if you go through a huge legal battle to accomplish it, that is harmful too.
