DS has just turned 2, and we've been using Motherease nappies, which we really like. He's a big boy, though, and now the nappies seem to be too tight around his legs, leaving big red marks. So, my question is this: do we just give up and switch to disposables now (which would make me shudder from an ecological perspective and also because it might delay potty training) or should we switch to another kind of reusable nappy, in which case we'd have to splash out and start from scratch, which is very expensive? Any suggestions would be appreciated!
