My little guy started getting frustrated with the bottle at around 10 weeks (I bf mainly and he only has a bottle if I’m at work) was crying, pulling at the test, I changed to the X ones and he was a lot better xx
I moved on about 3 months
Hi, my LG is 8 weeks & we have just changed to medium flow (size 2) we find she’s finishing bottles and napping longer. If that helps x
I combi feed but have kept using the newborn anti colic bottles and she’s absolutely fine and it helps to pace feed her so she’s not guzzling. If baby seems to get frustrated or is taking too long to drink the bottle then size up but I wouldn’t unless you feel they need it x
