LO is 10 weeks and we've been using CD for a little over a month now (we wanted to wait until he was big enough not to need newborn diapers). We're using bumgenius pockets and at least once a day he is peeing enough that they leak. He never goes more than an hour without a diaper change except when he's sleeping. At first I thought they were just a little loose, but as he gets bigger they're seemingly pretty snug and still leaking. Any suggestions on what's going wrong?
