I have recently started using wool at night and find it really good. We use puddlekins night nappies and weenotions night notions nappies with extra bamboo and hemp boosters. We use this regardless of whether we put her in plu wrap or wool. The plu doesn't leak but the nappy and boosters definitely don't feel as sodden when we use wool.
In term of the poppers, my oh struggled with them at first and preferred Velcro, but eventually I phased out at the Velcro nappies so he had to use poppers
I found what he needed was for me to show him which popper setting to use and a quick easy way to count across so he wasn't trying to work it out with wriggling baby underneath him
Whenever she goes up a rise / waist / leg setting I inform him and show again so now he doesn't have a problem at all.
