daycare moms - diarrhea (sorry!)

Has anyone's DC caught a virus from daycare? (I think it's rotovirus ) DS has had his 2 month and 4 month shots already.


He has had diarrhea since Friday
I was hoping it would be better by yesterday but it wasn't so my DH is taking him to the ped today. No fever, he is happy and playful, has been eating and drinking...

At first I thought it was because he had a reaction to introducing squash (he had no problem with sweet potatoes or the rice cereal)..but now I don't know.

He's been on Good Start Gentle formula for months, could it be an allergy that developed?
