I had my nephews here last night and in my 2 year old nephews nappy bag was a 2IO I made for him. I decide that since he's getting close to TT surely he can't be wetting through the night too much (well DS wasn't) I popped it on him to sleep in. I've been told the fabrics I use have been know to have problems before and to expect them to leak and I've also come to understand that if a nappy made with breathable PUL gets too full it can feel damp on the outside. Well it was FULL when I changed him this morning and not one leak. I was so proud!!! I'm so happy!!
