Do you use wool at night?? That could also help his nappies last a bit longer
(ETA sorry i just realised you had put about wool n your opening post
I ove our puddlekins nappies, the only thing i would say is that the one size ones are quite big and as your LO is tiny tiny im not sure if it would swapm him
Im sure if you contacted Ems though (when she has custom slots available) then she may be able to make you a tiny one rather than the one size
The bedbugs last Kieren 12 hours easily (although he doesnt sleep for a solid 12 hours as he wakes to feed etc...i just dont like changing him in the middle of the night as it wakes him right up rather than his normal 'sleepy but awake enough to feed state'!! I put one on him the other night when he was poorly at 6.10pm and we had an awful night and he didnt actually get up untill 9.20am and he was still dry under his woolies (outside of the nappy was wet but no leaks...) I think its ike anything...works for some and not others
Good luck, hope the other EP made a difference!!
