Id deffo phone and ask your health visitor about it, my lg was being fussy on the bottle a few weeks ago and I changed the teet to medium flow and now she drinks 2x more per feed, have you tried this?
@Lynds yeah shes been on size 2 since just before she was 3 months as she was collapsing teats and you could see she was working harder to get it out. I dont mean like offering her 2oz or anything like that just a little sip here and there x
Personally I wouldn't as water holds no nutrition value and if she hydrates on water she might end up drinking even less milk and they need milk the most, when making a bottle its good for an hour (I do an hour and a half) sometimes she rejects it after 2oz but from that point every half hour I offer it again and she'll drink even more of it, at least you know she'll keep well hydrated and shes getting plenty this way
@Lynds yeah thank you! I do keep it but she just pushes it away and gets annoyed with me 😅x
Shes formula fed only too
