A note on Simply Nights sizing: With the extra hemp on these diapers, if you are on the fence on a size or anywhere near the next size, I recommend you choose the next size up. The extra layers provide a more snug fit than other Very Baby diapers. Also, if you are considering medium-long, chances are that you need a large. Please contact me if you have any sizing questions!
