Lizzy is tripoding. Tripoding is when babies are trying to learn how to sit up, and they use their hands for balance--like a tripod. They are still tippy (hence the boppy pillow), but they can sit up like this unassisted for a few seconds to a minute. I discovered that she can do this last night, and I was SHOCKED, because all my baby books list this as a 6 month milestone. People always tell me that she's strong for her age, but I don't think I really believed them until just now. She's only 3 months!
