Sometimes a kid isn't ready/interested in potty training for whatever reason, but still likes to take his pants and diaper off and make a mess. This is what we do if he needs to be put in his room for a nap. Please, no comments on how it's time to potty train him... I don't want to discuss it.
a toddler who keeps taking his pants off
zippered, footed pajamas
Step 1: Cut off pajama feet
Step 2: Put pajamas on toddler
Now he can be put down for a nap without you worrying about washing all his blankets, pillows, and sheets later. :)
