hi, my almost 2 year old has been complaining about being sore when we change his nappy. at first i thought he was just getting more aware and didnt even know if he knew what sore meant but he keeps saying it so today i pulled his foreskin back gently to make sure it was clean and it doesnt pull back far at all, it also obviously hurt him. should i take him to the gp with this? is there anything they can do about it? thanks
