Best Bottom One Size Diaper Cover / Ai2 (All in Two)
We recommend 3 inserts for every one shell. Three different size inserts in several different materials available. We don't believe in a one size insert. Newborns and toddlers are not the same size so in order for a one size insert to absorb enough for a toddler it will be HUGE on a newborn. You may not need all three sizes of inserts and can skip the middle size - it is all up to you! We recommend approximately 24 inserts per size. So to make it simple you will need approximately 8-10 shells and 18-24 inserts per size.
Sizing: from birth to 35+ lbs. We added special leg gussets to help keep everything in, adjustable rise with four settings, and overlapping closure in both snap and hook & loop. This is a very trim fitting diaper so please be extra careful that none of the insert is sticking out of the shell. Also, after the diaper is on, pull the leg gussets out around baby's legs. This will guard against leaks and help avoid any red marks.
Please note that most covers have just a PUL waterproof outer, however there are some that have a layer of cotton over the PUL outer and those are noted in the options.
