Re: best diaper for baby w/ hernia?
My youngest had really bad reflux as an infant and we had to be super careful with our cloth diapers because anything constricting would make him miserable. We were able to do diapers with stretchy tabs like BG snapped on the lowest rise once he was big enough. You might also consider Green Acres design with front elastic, they don't squeeze tummies at all and are super gentle.
Leaving DS so I can spend less time on the computer and more time with my family
