Willa and Oliver are not too crazy about rolling over. They can do it, they just don't feel like it very often. So I have to force them on to their tummies every day, and eventually they get mad enough to roll back over. They hate tummy time, which makes me hate tummy time, but I persevere. Kate, in the meantime, is rolling all over the house.
Surprisingly, Oliver is just as good as Kate at sitting up - he is so close to being able to do it on his own. Willa just topples over. However, she has a second word now - "ba ba" - referring to her bottle. I swear she knows what she's saying!
