Emily loves to play with her own hair as she falls asleep. Sometimes while I'm feeding her, she runs her fingers through her hair and I've noticed her doing that as she tries to settle herself to sleep. I like that she does this because unlike a pacifier which can fall out, her hair isn't going anywhere!
We also have noticed that Emily likes to take things out of their containers. She loves taking her socks out of her drawer and she loves taking her toys out of her cube. We pack it full of all kinds of toys and laugh as she figures out how to open the cube and take every last item out.
