LO is 14 months and moving into size 5 Target brand diapers. It's not an issue of weight, but more his height and hips I think.

From what I can tell from checking out all the brands in the store, diapers only go up to size 6, and at the rate we are moving through the sizes, we should reach there quite soon. So as a clueless first time mom here, what happens if you go past size 6? Did your LO slow down and stay in size 5-6 for a bit, or did you have to go to pull-ups? We won't be doing any potty training for quite some time.
