Now, going to ask what is the hardest diaper or most stiff when dry or wet? Thank you all for your input, it helps to find people who have tried different types already.
NorthShore Supremes, plastic backed are probably the most stiff diaper out there. They're awesome quality too, and you can always fluff it up slightly if you want it softer. The lining is soft but the padding comes rather compressed, so it's stiff. Try them out!
