Sooooo..... lately Little M has been sitting and playing on the floor, with a tiny smattering of trying to crawl thrown in there for good measure. When I sit on the floor with him, he sometimes gets it into his head that my knee looks really tasty.
When he leans over to start sucking on it, I usually laugh and shriek pretty loud, because I'm really ticklish there. So today, he was just sitting on the floor playing and we were laughing, so I laughed the loud shrieky laugh just to see what he'd do, and Little M then leans over and starts sucking on my knee! So cute. And weird.
