Potty training 101

So I decided that Carter was ready to be potty trained!  I bought him 3 pairs of Toy Story underpants and put them on him early Monday morning.  Within 15 minutes he had peed through them.  I changed him and we read the potty book along with review his rewards if he peed on the potty.  I began to sit him on the potty every 30 minutes.  He would sit there, watch TV, and read a book.  I am telling you that literally 5 minutes after that whole procedure he would pee in his underpants.  We went through the three pairs in less than 90 minutes.  I decided to them just let him run around the house in the nude.  This strategy didn't seem to work either.  He was still peeing and pooping everywhere.  I spent most of the day cleaning up the floor.  I noticed that he would tell me after he was finished but didn't really seem to know that is was going to happen.  I spoke with other moms the following day for some insight in what to do.  A mom demanded that I stop because I was emotionally damaging him.  He is unable to control his muscles down there and she said I was punishing him for something that he had no control over.  I thought about this and decided she was probably right and that I was trying to push him to doing this instead of waiting until he was ready.  So we are still in diapers...
