Do you have a heavy wetter?
After doing endless research on my own son, who happens to be what I think is the heaviest wetter out there, I thought I'd share my thoughts on how to get a heavy wetter through a complete night (12 hours) without any leaks.
I used to tirelessly try to make an all-in-one work for me as an overnight solution. Unfortunately, there (a) isn't nearly enough room to add the amount of stuffing we need and (b) there isn't nearly enough hemp in any all-in-one...in fact, very few all-in-one diapers have any hemp at all in them!
Are you detecting a theme here...hemp, hemp, and more hemp. That is your only solution for a heavy wetter. Unfortunately, there is no way to get through the night without any leaks AND keep the diaper trim. My poor son looks like the Michelin Man walking around with his nighttime diaper on - of course I usually don't put his nighttime armor on until I know he's going to bed within the next 30 minutes or so, so he doesn't do too much walking around!
One thing you need to be careful of, especially with boys (other than to make sure he's pointed down!), is to not stuff the diaper so far up the front so that the diaper waist is pulling away from the baby's waist. That is a surefire way for him or her to leak out of the top of the diaper. This is more for those fitted diapers that do not have pockets - where you have to lay the extra hemp inserts in the diaper itself or underneath a sewn in insert.
