It doesn't seem to me like he has hearing problems. When you make noise he notices. He does coo and babble. No he really doesn't try to make eye contact, you can make it with him but hes really not interested. Lastly he will fuss and you can tell he wants something but you have to offer him something (i.e. food, toys, a drink) before he is satisfied. I failed to mention he is constantly sucking on his botXXXXX XXXXXp.
