Teets

12 weeks. If they r showing signs just give it a go try it for about 3 days takes a while for them to get use to it. But always do it off ur babies cues and not age x

15 weeks. I changed teats when she would fall asleep on the bottle more, seemed like she had to suck harder to get milk, was fussier than usual and rooting while the bottle was in her mouth

My daughter was 16 weeks when she went up to size 2 she's still on size 2 now at 6 months as the next size is too fast x it's when you think they're ready x
