For newborns, I’d focus on a diaper that fits well, feels comfortable, and keeps the baby dry rather than choosing based only on the brand. I used MamyPoko Newborn Diapers for my baby and was happy with the fit. For changes, I’d check regularly and change whenever it’s wet or soiled, especially for newborns.
I change every time after feeding. Cos my baby keep poo when drinking. Merries and rascal and friends is good!
