I've just changed my little boy who is 1 year old and noticed his has 3 or 4 spots on the end of his willy. It looks red around the end and the spots are white and quite big. They don't look pussy or anything. They have all come up within in the last few hours (my partner can't remember if he saw them this morning) Any idea what they could be? He has a little bit of nappy rash. We don't have a doctors appointment till Monday.
