I am just writing this as I have at least 3 friends who spent hundreds on a set of reusables/ cloth nappies, byt they leaked so much when bubba was tiny that they chucked it in and have a cupboard full of nappies. I just thought the other day (DS is 11m) this is so much easier!! We started using cloth nappies at 3 months and I had moments when I thought aaargh!!
I think it's because he now drinks less liquid so there are less leaks. Also the poos are usually more solid so there's less contact with the brown stuff and less hideous explosions to deal with. Just wanted to send encouragement!!
