My son does the same thing whenever I size up the nipples I usually pace feed when I notice that. If you hold the bottle at a more horizontal position it doesn't fill up the nipple so much that he just chugs the whole bottle and he's getting a little bit at a time. You can also try to take more breaks when feeding like an ounce or two give him a few minutes to digest that go again take another break. It can be difficult if he's a fussy eater my son will get mad because he wants more which is why the pace feeding works better for us.
Size 2 takes 10 mins x
My little boy is the same, size 3 he demolishes but feel like it’s heavy on his tummy and he can be quite sick from that, size 2 he takes around 10 minutes, maybe continue with the size 3 and see if he adapts? Is he sick when he feeds normally or is it just when using a size 3?
