Need a Disposable Diaper Solution for a Size '7'

Hi Moms, I need a disposable diaper solution for a child that has essentially outgrown Huggies size 6 diapers (and is allergic to Pampers Cruisers size 7). My child just turned 2 and is not quite ready for potty training, therefore, I need to find a diaper solution that is bigger than his current size 6 to accommodate his waistline. Any recommendation would be appreciated, thanks!
