The father would have to convince the judge that he is responsible. This may be hard for him to do.
Courts tend to want children to have both parents in their lives, and often overlook things such as irresponsible behavior (if it doesn't put the son in harm's way). But every other weekend sounds like enough time, courts might side with you on this one.
I wish you the best, please let me know how it goes. Sorry I don't have a better answer for you.
