If you look at the picture to your right, this is where Andrew usually plays peek-a-boo. Right around that wall is their bedroom. So Andrew will poke out his head, crawl into the bedroom, then return sticking his head out from the corner giggling like a jolly Japanese girl visiting Disneyland for he first time.
Today, Andrew was playing peek-a-boo with me at this very location. Andrew stuck his head out, giggled, then retreated to the bedroom. Again, Andrew stuck his head out, giggled, then retreated to the bedroom. One final time, Andrew stuck his head out, giggled, then instead of retreating to the bedroom he slammed his head against the wall.
At first, Andrew looked shocked. He had no idea when or how this wall appeared. Then his little face twisted into a face of anger and pain. He wanted to sue the construction company who built this wall that hit his face.
I picked him up and after a little cuddling and Cheerios, he calmed down. Hopefully, Andrew will be a little more careful the next time and take heed to the wall. Although I don't think Andrew has forgiven the wall yet because he just peed on it.
