Toddler Q: toilet training, my son is 2.5 years old and is 100% trained when he has nothing on is bottom. If I put underwear or just pants on him he decides it's ok to go to the bathroom in them... I'm 26 weeks preg and really want him to be finished being trained b4 this baby comes.... Any tips would be helpful. (He gets 2 cc for going to the bathroom)
