What formula if aptamil upsets tummy?

[JustLetMeSleep]

I've been trying to wean DD2 (9 mo) onto aptamil first milk but it gives her terrible vinegary watery poos. What should I try instead? She has cheese, yoghurt etc. with no problems so I don't think it's the cows' milk. Should I try comfort aptamil? Or a different brand?

Aptimel first milk or the follow on (no 3)?.
The first milk (no 1) is aimed at under 6 months.

The first milk because I read that it doesn't matter, they can have that at any stage and I thought it would be easier for her to digest than going straight to the follow on milk.

You could try cow and gate comfort milk, I found they milk was fine for my son who struggled with Aptimal!

The formulations as different between no 1 & no 3, just like your breast milk changes as they get older.

Might be worth trying no 3 (plus you can get reward points / nectar points / club card points etc for no 3 which you can't with no's 1 &2 )

Aha, ok thank you. DD1 had aptamil 1 which is why I tried that first, but she was 6mo so I guess maybe it suited her better. Will try the cow and gate comfort as well, thanks!
