potty training

I'm in the process of potty training my one year old son. I thought it was going to be easy, but it's not. One reason is the amount of milk he is given at night and if I don't give any milk before bed he will not go to sleep or he will wake up in the middle of the night. Also his nursey is not helping out like I would hope. I'm trying to get rid of diapers and not use pull-up's, but instead go straight to underwears. I did try a couple of nights, but it was a disaster. I went online to get tips about potty training and many expert said to get the potty that plays music. I did, but he stay on the potty long enough. Then, I start to think is my son to young to get potty trained. I'm a teacher at La Petite Academy and the kids are usually in the potty training process at two years old. I start everything early with my son like reading, talking, and now potty traiing. H e is developing and all other areas, but he is not trying to go the potty. His dad tries to show him, but our son just run away. He is too playful and maybe too young to be potty trained.
