It’s cas she does not eat hardly any food so she still needs her milk X

You don't give both formula and cows milk I don't think. Id Stop the aptamil keep her on blue top just make sure she has enough water in the day too xx

Full fat milk made my daughter have an upset tummy so we put her on semi skimmed and she was perfectly fine x

I don't know what milk to suggest but make sure she drinks plenty of water too and is getting enough fibre in her diet and that should help her xx
