Many other brands of diapers are now making a size 7 diaper which is good for bigger toddlers and even older kids who wet the bed or have incontinence.
Most size 7 diapers can easily fit a 5 year old, 6 year old, 7 year old, 8 year old, 9 year old and sometimes a skinny enough 10 year old.
My 7 year boy wears size 7 Pampers Cruisers for his bed wetting and when away from home as he has trouble making it to the toilet soon enough and it's hard to find public toilets now.
