Following as same issue….
Upped all mine before the “ age “ on the box. Done the world of good, happier baby’s! You’ll know when it’s time without even realising xx
I use the same bottles and we went up to size 2 at 6weeks. My LO is so much better feeding now and drinks more without getting frustrated
I would move up a size We had the same issue falling asleep and not taking much milk Once we went up a size she started taking almost double what she was
We went up to size 2 at about 7/8 weeks. We use both size 1 and 2 now just because we have them and noticed a big difference in how long it was taking him to finish, on both sizes x
