Hello girls! The child has cold sweat, nothing bothers him, he just sweats profusely during feeding and when sleeping, cold sweat. Please tell me, please ?? I'm looking for a good pediatrician, the current one doesn't suit me. Just anyone who had this? Or is it because of a lack of vitamin "D"? I don't give any vitamins, I would like to give them in the future, how do I find a pediatrician?
