My six year old son

So it's 1:30am and I up because my son started a fever earlier today and his fever decided to get up to 103.6 degrees and I gave him medicine and put a cold towel on his head hoping that in a little while it will go down. My son is sleeping but it makes me so nervous. I don't take him to the we because every time we have taken him for fever we sit there for hours and they tell us to give him over the counter medicine then I get a bill for some over paid doctor to tell me worthless information!!! While I up with my sick son I can't help but think when baby #2 is born and my son gets sick or my baby gets sick they will probably get each other sick and boy does that make me feel scared!! Being a mom to two is going to be a challenge :)
