Toddlers that Won't Stay Dressed or Keep a Diaper On

I have a toddler that if it snap or zips it's off before you even notice. Next goes the diaper.
For evening we like to wear warm jammies. Well, I have cut off the feet and put the jammies on backwards and it works awesome. If there is elastic band at the ankle I just cut below it. My daughter can wriggle out of just about anything but not the backwards jammies. It keeps the warm clothes on and the diaper on.
