Seablue, we have that *same* thing happen regularly! DD2 will say she has to go, so as long as I'm there I'll go too, but she's done so she just tries to leave, lol. We have to keep hook and eye locks on things like the pantry (she will scale the 7ft shelves to get to the good stuff on top). She's been able to lock and unlock the front and back doors since she was 15mo, now she understands she can't leave the house without an adult, but there were a few months there where I was grateful that we have an alarm with door chimes.
