Thank you both, @tg123456789, we had to change his teats from 2 to 3 as 2 was to slow for him he was sucking so hard he was getting frustrated and loads of wind and 3 he's fine with but is gulping it down xx

hetties was like this for around 3 weeks and we had to take sample into doctors as they couldnt understand when was explaining it and apparently its the milk not been digested properly. was told we wasnt shaking it up properly or she was wolloping the milk down too fast.
we knew it wasnt the forst so we changed her teats to natural flow and the right size ect and she is fine now @lucxo x

mine had a bit tye same when i started bm again but it changed again. i think because he has been dribbling a lot aswell. but im not sure hun all babies are diferent mine aeemed fine but for some that could be diarrhea xx
