I'm curious how much difference there is between the Level 4 and the Y cut bottle nipples.
We've already moved our 5 month old to the Level 3 and obviously the next step won't be far off. The package for both the 4 and the Y say 9 months+. Anybody try both? Is the flow much faster with the Y?
I just figured if we could skip the 4 and go straight to the Y it would save a little money.
Thanks!
