My ds2 is 1 week old and when i change him after a poo and wipe the cotton wool underneath sort of the back of his ballbag (scrotum??) he really cries. He had his new born check on tuesday with the gp and when she checked them bits he was fine. Checking for distention or whatever it is? He didnt cry when she prodded about. I use cream every time i change him and cant see a rash, looks abit red but then not sure exact colour should be anyway. Any ideas?
