Rash/ food allergy question update x 2

Monkeybutt80

I knew this would happen the first time I introduce multiple new things to him  

So he had something new last night;  a little bites of strawberries (about a quarter of a regular size strawberry) and then this morning he had pureed pineapple with cereal.  Daycare just called and told me he has a rash on his belly and I have no idea if it is the strawberries or the pineapple.  Neither family has any food allergies.  

My first thought is that strawberries are more allergy prone, but he had it last night.  Could he develop allergic reaction to what he ate the night before? or is it pineapples because that's what he had an hour or two before his rash started?

And finally, what do it do?  just leave it and watch if it spreads?

Thanks ladies... 

Update:  Called our pedi and he wants us to bring him in.  He said it may even be something unrelated to food such as strep. He asked if he had any other issues lately.  As I said in my TOAT this morning, he had not been sleeping well, very irritable, and had a fever friday night and saturday night. Because his tooth broke through overnight on saturday, I thought that was the culprit and that the next tooth was working its way through.  And he's had congestion in the past 4-5 days.  Now the Dr. wants to make sure it's not strep. I will be bringing him in after my meeting at 3.

Update2: we just left the pedi office. The dr doesn't think it allergies. Like @elmoali said, considering the fever and congestion, they believe it is a viral infection related rash. It will go away on its own. Unrelated, he has an ear infection. So over the weekend he had an ear infection and a viral infection and cut his first tooth. No wonder he was so miserable!

Is say pineapple. Ds1had a reaction to cinnamon and his showed up right away.

It depends.  A deep gut allergy can take a while to show up so it could be either.  Back off of both for a couple weeks and then reintroduce one, wait a couple weeks and then reintroduce the other.

Ah, I didn't see that he'd had a fever over the weekend.  Rashes and fevers are common together so I'd bet he has a virus.  Hope you get some answers and he feels better soon

Could it be roseola? I hope it's nothing major.

Thanks you ladies! The rash is still there but he's doing better! He's now on antibiotics for his ear infection so hopefully he won't be so cranky! @clearskies77 thanks for the info. For now, just in case we are going to stay away from both pineapples and strawberries just in case and until he gets better, we will stick with what he's had before. @elmoali you were absolutely correct! I had no idea virus/fever could cause rashes. But at least the rash doesn't seem to bother him!
