Apparently size 3 are super super fast and a lot of babies struggle with it, so I’d maybe delay if possible. My baby is 5 months and still on size 2. Sometimes they go through a stage of just being easily distracted. Could you just let her drink as long as she wants and then burp her when she’s finished? Mine started doing similar to yours for a while and I just let her carry on drinking until she told me she was done and burped at the end.
@Siobhan yeah we don’t stop her drinking to burp her we’ve always waited for her to stop herself 🤷🏼♀️
My little one was starting to get that way with his bottles and he's 3 and a half months old. We switched to the size 3 mam teats a few days ago to test it, and he's now brilliant! Back to his happy self taking his bottles with no problems again 🥰 he had been getting frustrated with his bottles for about 2 weeks before we gave in and tried the size 3 teats.
He's also gone from taking 20-30 minutes to drink his bottle to taking 5-10 minutes now that he's on size 3 teats. He's definitely happier in himself now thanks to it, and a lot less fussy.
My little one had a tongue tie which we saw a specialist for who also advises on lactation. With the correct latch it is supposed to take 25-30 minutes for a bottle feed with paced feeding. If it is too fast they can take on air, not register whether they are full or not and also certain digestive enzymes may not be released causing the milk to ferment in their tummies.
Sounds like she needs to size up, I’d just recommend pace feeding for a week or so with it so she gets used to it. The guides are just a guide, all babies are different feeders x
