Stomach bug?

Angelica • June 2016👶🏻💙

So my son has thrown up 3 times since Tuesday night. He threw up Tuesday night because he has some stale French fries we didn't know were stale. But ever since then he's been throwing up when we give him his bottle! He takes regular whole milk and we always warm it up in the bottle warmer. Yesterday morning we gave him a warm bottle and he threw up. Yesterday afternoon/evening we gave him 2 bottle right out of the fridge (ice cold) and he kept them down. This morning when I tried to give him his bottle moderately warm, he threw up again!! Plus he HATES pedialyte!!! Any advice or suggestions?!
