My daughter was prescribed Aptamil Pepti 1 for suspected CMPA and has been taking it since Friday. She is mostly breastfeeding but has 1-2 bottles of formula per day. She’s not a fan of the new formula and is putting up quite a fuss when drinking it so we are only giving her small amounts to try and let her body and tastebuds adjust. Since she has been on it she’s had really loose and smelly poos which I understand is expected when transitioning.
She had one bottle yesterday afternoon at around 2pm and no second bottle in the evening and I noticed her poos returned to a more “normal” consistency last night and this morning. She just drank about 70mls of the formula and within 10 mins was squirming in discomfort and did a very watery browny poo. Is it normal for the formula to have such an instant effect? I thought it would take a few hours to get through her system.
Has anyone experienced the same thing?

Sometimes the reaction is really quick, I did find that aptamil pepti 1 still has the proteins in it, just broken down. We had to go on specialist prescription milk completely free of milk proteins to finally be done with the discomfort. And we had to add carobel (thickening agent) to it or he would spit up endlessly. But too much carobel and he'd be instantly constipated. Feeding took a while to figure out tbh

Ah ok good to know - thank you! I’ll give the dr a call to see what they recommend as a next step.

thank you!
