At 2 months would frequently spitting up be a sign of a upset tummy? She has been a little fussier than usual but no fever , no diarrhea . Its been going on for about 2 days .She doesnt seem to be in pain just spitting up more than usual .

She is breastfed , could it have been from something I ate .

I'll be calling ped in morning just wanted some opinions.
