I tried happy heinys, bum genius organic AIO and moomookow when my baby was 1.5 m.o. I decided to stash up on moomookow because i like the inner suede layer which stays dry, it fits my baby well plus the price is great. HH has the same cutting as MMK but i dont know why it always leaks immediately after he pee. the inner layer is softer than MMK too but i find it worn out quite fast. so MMK is more durable i guess, after more than 9 months of regular wear. bum genius can last longer, good for night time and it is more fit and trim for my baby than MMK and HH but the snaps are terrible. I broke the 1st snap after only 1 month+. Now it has poo stains which are impossible to clean.
