One of the challenges we've faced with Joe is keeping him from getting into his diaper (and creating chaos with his feces) when he is dirty - especially at nap-time before we get him up. We have tried a series of things before finding one that seems to be successful. Here is the progression of our
Attempt one: sheet corner fasteners
Attempt two: cloth diaper snaps
Attempt three: onesie conversion
Inspired by this "onesie extender tutorial" post titled "Seriously, Keep that Diaper On", I cut the crotch strap off of some onesies and sewed them onto a few under shirts. This has been our best solution yet. They are wider than previous attempts and its easier for me because the snaps are already in place and I don't have to fiddle with a clamp trying to attach the snaps to the fabric myself.
Joe seems to tolerate it very well. The only thing we've come up against is that he will sometimes hop out of his pants during nap-time and then have access to the diaper via the side. So we currently will snap the "onesie" over the top of his pants which keep the pants in place and his hands out of trouble.
So far this is working for us. I would love to hear of ideas other special needs families have used. Any suggestions? ;-)
