I'm pretty decided we're going to go over to cloth, but I can't get my head round what we need. Ds2 is about 14.5lb, he's aged 4 months, and quite long and lean. From talking to friends, I think we'll use totsbots nappies, and motherease airflow wraps, but can't work out what size wrap to get - there seems to be one from 10-20lb, or 20-40lb. Now he obviously fits into the first category, but I don't want to spend loads on wraps, just to have to replace them in a few weeks. Any ideas? Thanks!
