Oh no...

So I used to let Corbin sleep in just a diaper, because we have no AC and it does get hot in our house. Then a couple of weeks ago he learned how to take off his diaper, which resulted in a disgusting mess, thus ending his days of being allowed to not wear pajamas.

Then this morning, I went in his room to get him up and this is what I found:


Now we have another problem, as he has learned to take off his shirt, pants and the diaper. He was so proud that he had taken them off all by himself. Luckily there was no gross mess... this time. Do I duct tape them on? He doesn't seem to understand the importance of leaving his clothes (especially the diaper) on.
