Perhaps start your dh with some AIO's like BBH Magicalls? Same shape as a disposable. (I'd suggest ittis, but they have snaps and some dh's are resistant to snaps at first.)

My DP loves the snaps as he knows how what clip she needs them on and therefore cannot do it up too tight unlike with velcro... he will put on her BBH Fitted night nappy but leaves the wool cover for me

I 2nd, 3rd, whatever we are up to. I use Itti Bitti's by day and BBH fitted by night and I love them, DD can last her 14 hour sleeps with no leaks!
