Hello, Thank you for using HCM. By what you explain it seems very likely the child is getting frequent tonsillitis due to being more in contact with viruses in the day care. When children are first introduced in day care they do have a period of months that they get sick more often than usual due to contracting more viruses and germs that might cause infection. This is a normal process of her growth: she needs to go through those times to build her immune system and gain protection against those viruses so she should not stop attending day care. It is important for parents to understand that it is expected and is normal. Most of the children do get fevers and tonsillitis and other infections that are self limiting and have no need of treatment other than fluids, medication to help with fever (paracetamol, ibuprofen) and rest (avoid day care up to 24 hours after last fever). Sometimes the child might also need antibiotics and a visit with a doctor will make this easier to decide but most of the cases those infections should be self limiting. She might also get stomach viruses and get vomiting and diarrhea and sometimes even skin rash- she needs to see a doctor in those cases but those might happen also. Crying is very unlikely to cause the tonsillitis and combing her wet hair does not seem the cause either. You seem to be doing the right things with her, giving her a healthy diet and this should help enough to boost her immune system and the contact with the viruses is giving her the experience and the antibody to fight infections. There is nothing else recommended to help her immune system. Hope this is helpful and answers to your question
