Yeah sleepers are the best. Hannah is wearing a monkey one right now lol. I love them. But I would suggest zippered sleepers over the snap button ones. I have had both and don't have a problem using the snap buttons but then she wakes in the middle of the night and I have to try to figure out these stupid snap buttons while half asleep lol.

and onesies... LOVE onesies. they are great for when it's cold out too. put them underneath a top or sweater and it provides layers to keep them warm and prevents their belly from getting cold when you lift them up and their shirt is up to their armpits lol. and they are great in summer for reasons already posted above.
