My son is 5 year 6 months. I have been giving potty training to him from last 2 years, but he don't want to go in toilet.. He was got well trained and routine was set. since few months he again started doing little toilet in his pants and also he is not willing to sit in toilet. He avoids conveying us about toilet. sometimes he does not understand that he has done little toilet in his pants. plz suggest a solution to this. or is it that this wi go with his growing age...
