Kissy, you have my sympathies. My now 5 year old got Social services called on us twice for his disappearing act, and once for his death defying leaps from the back of the sofa (which was in front of the slider, so the nosy neighbors could of course see). His escape tactics wee a real treat.
The first one was when he was 2 and a half, and I was pregnant with Gilly. Me and him were snuggled in my bed watching blue's clues, and I started feeling that ole morning sickness, so I ran to the bathroom. Not 2 minutes later (I'm not even done in the bathroom), there's a knock on the door.
By all of the most amazing luck in the world, a social services worker was driving to visit our neighbors, and my son managed to unlock the front door, open it, and the unlock the screen door as well, and run out into the yard, and then road. We lived out of the way, on a dirt road, so traffic was few (thankfully), but still.. of all the luck, it was social services.
BTW, we've learned that flat paint is just hopeless with crayon, and Goo Gone get's it off of most glossy surfaces. He was also our budding artist- on the walls, mirrors, pictures, floors, refridgerator, dressers, windows, etc. You get the idea.
It does get better, but lord, I was down at the end of my rope, praying for help when I finally had to call my family, and tell them they needed to work out something to take him off my hands for a few days. I felt so helpless, and rotten, because I thought I was a horrible mom for feeling like I couldn't control my child, or my feelings towards the situations.
I am SOOOO glad he out grew those days, but boy...
Anyway, you have all the sympathy in the world from me. It's hard being in that position, and not knowing how to stop it, or when it will end.
