Don't feel bad. My son turned 3 in December and is at the exact same place as yours potty-wise. He is really interested in learning things and doing things that he just couldn't care less about potty training. I swear the kid will be reading before he poops in the potty! I have a 12 month old daughter too, so I understand your difficulty in dealing with two. I think we both just have to have faith and trust that one day they'll show a stronger interest. I am not pushing my son until mid-late summer. It'll happen. Good luck.
