I've been doing some research on this for non-*B/DL story-writing purposes, and I've noticed a HUGE difference in "size 6" toddler/child weight range for Huggies and Pampers between North America and the UK. In North America Huggies size 6 is listed as 35+lbs, whereas in the UK, the size that they call size 6 can fit young primary school children up to around 66lbs! I cannot see a North American child attending fourth grade wearing a size 6 Huggies diaper, but in the UK a year five student wearing a size 6 Huggies nappy seems somewhat doable.....and a child would seem to be growing into a "youth" diaper sooner in North America......which is odd because up until recently it was the UK kids being taught to use the potty sooner than those in North America (18mos-2yrs avg in UK, 2 1/2yrs-3yrs avg North America, from what I've read). So why is this difference so drastic? Although I'm not saying it's ideal shouldn't NA have the bigger sizes? Opinions, facts on the diffs, guys?
