DS had his 1st fever and 1st really significant illness (strep throat) last week. He had a fever for 5 days. He barely ate anything for 4 days (maybe 1 yogurt per day and 1/2 his usual milk intake). Ped said not to worry that he'd make up for the not eating as soon as he felt better.

Well, this week DS is back to eating but the amount he eats is WAY down. He's also not drinking all his milk which is unheard of for him. He barely wants to touch his lunch or dinner. I'm worried, I don't get it. He was a great eater/milk drinker so I'm baffled by this. He's still on the Amoxicillin (the pink stuff) could that have anything to do with it?

Would you call the ped? He's 19 months.
