I believe with every child there parents need to make sure they know exactly whats going on. Like I can tell when my daughter is getting sick. And since she was born because of some difficulties after birth she has a low immune system. So when we get around people she dont know or total strangers she gets sick totally and we sometimes end up having to take her to the doctor or to the hospital to clear the infection up that she has. Allergies I think are the worst of are problems because when a child gets sick with the cold or the flu its going to go away in a period of time with allergies they dont go away and we have to nurse those allergies more and more. And our children dont like them and we sure dont like them. Allergies make things seem worse then what they are. But We should as a parent know the health of are child. And keep a straight eye on how they react to being around people. And teaching them to lead a cleaner life for if we dont the health of are children wont get better but worse we are parents and parents need to watch everything they need to know and keep track of what they had and when they have it. I my self keep a medical diary of my families health because if I didnt then when we went to the doctors I couldnt tell them anything except the few symptoms that she has on a normal basis for a cold or flu or an ear ache!
