its not going to hurt to let him go commando for awhile in the house just pants outside of the house. I am potty training to and going commando makes it easier to catch. I had to let him go commando for a while before he would agree to go to potty pants which took about a week. let him pick out his own big boy pants at the store. characters are the best and he picks his favorite character. when the first one trains the second will get jealous and do it too you are on the right track. he may need boxers too. most men wear boxers.
