He may be weaning himself. I know I weaned myself by 3 months and was on formula & baby food....my mother reminds me how disappointed she was at not being able to do it longer. My 1st son was weaned off by us parents at 2+ years old and we still have issues with him eating anything. I'm just started on #2 who is now 4mo and still breastfeeding....who knows what he'll be doing! LOL
Don't worry about it, some kids just prefer regular stuff and some don't.
