@lill-Mac, have you tried the InControl BeDry? I've used both, and they're a pretty good stand-in for a BetterDry. Or maybe look into if the printed version of the BeDry, the Crinklz, ships faster? I have these in my inventory as well, and they perform identically, they just have baby tigers etc all over them. Literally the same diaper.
Update: Huggies Pullups has just quietly unveiled 6t-7t. It also looks like they made a change to the core that they added a quick wich layer to it. No eta yet on release. Cannot preorder currently
Also looking at the weight puts these even larger then the 6t7t Easyups.(im still secretly waiting on the day the adult size comes out because incontinence is a real problem for some)
When I first moved in my house, I had a million holes in the rim joists that my basement was around 32 F (0 C) in the winter. I filled a lot of them, now it's at least 57 F--it could be done more better I am sure. Since it's over 30 years ago, I don't remember how much my heating bill was.
