Re: The one thing I hate about CDing...
Is your insert hemp? Can you wrap the hemp insert in a microfiber towel? That is a great solution. MF absorbs quick and hemp holds longer, a great combo for overnight. I like an infant prefold with a hemp insert under stuffed in my pockets. That goes all night too.
I never have had one wicking issue with my 14 mo old, ever. He has been in CD since day one. I use pockets and I use pf or fitteds with covers.
You could also fold the micro fiber towel (the dollar tree one is a perfect size as is) upfront where he needs it to absorb most...
