OK. I don't have any advice for awake time, but had a houdini myself about 2 yrs ago. This will only work until she is potty trained at night and/or you don't need it because she loses interest. You need zip pjs. Get a baby safe safety pin and run it through the cloth on both sides of the zip and through the notch in the zip. This works on both winter and summer weight pjs...but it DOES mean no cute princess nightgowns. Mine never had the strength necessary to manipulate the safety pin and open it, so it was NEVER opened when we came back in the morning. It saved me a lot of laundry. And after an incident of painting with poop (she and her sister covered each other and their whole room with the poop from her diaper one evening), it saved me from selling her to gypsys. <g>
Good luck. Wish I had an idea for the day.
