OT: Baby/Toddler won't keep diaper on...

My two year old is currently doing this, too! I wait for the b.m. before putting him down for nap. Twice he's "painted" his crib, walls, etc. So, I wait for the b.m. and that takes out that possibility. Then, I put on the diaper backwards and footsie pjs with the top snap on backwards. So far he hasn't figured it out. If that doesn't work for your dear little one, can you try a backwards diaper, then duct tape all around, then backwards footise pjs, with a safetypin through the zipper hole onto the clothes? Also, she's probably old enough to understand diaper on = reward, so that may motivate her.Good luck!Natalie
