Hi hope about 2 years ago, ittis formed the bulk of my stash. They are good until bubs becomes a heavy wetter, usually as they get older. When DS was about 2, he could blow it out with one wee. We also got horrid wing droop so switched to side snapping nappies (which is my stash now for my 2 older girls)

I have a small itti here and my youngest is nearly 3 weeks old and it's still too big for her around her legs. Waist wise and rise wise it fits fine, just not her legs.

I use a mixture of ai2's and flats for the older 2 girls, and a mixture of fitteds and ai2's for the baby. I think it's personal preference which is better, I'm not a fan of pockets as most these days are lined with suedecloth (which gives us nappy rash) plus I got sick of stuffing them. It's easier to snap an insert into a shell than to stuff a pocket - and these days - I'll take the easy way out lol
