My 19 mo's cloth diapers fall off if he isn't wearing a onesie, especially if he poops. We use pre-folds, our only option as we don't have washer/dryer and must use a service, and the covers we use are lite-wraps, basic velcro cover. We have several different sizes of covers, and both fall off. How on earth do you get cloth diapers to stay on at this age? He's in 24 month size clothes, and I'm having a hard time finding onesies- and I don't know what I'll do when he outgrows those in a few months!
I'm really frustrated with cd'ing right now...luckily my dh manages most of the diapering, or my poor ds would be in paper dipes!
