Ugh I think I messed up :(

Br

My baby has IBS and we switched her formula from elecare to puramino and I wasn’t even thinking and started her on oatmeal. Now her stomach hurts 10x worse and idk if it’s because of the oatmeal or formula. I hope it’s not the formula bc the Elecare wasn’t helping her that much either and I was praying the Puramino would at least help a little :( I feel so bad now idk what to do I’m at my wits end
