Sophie seems to think she's a big girl. She's always trying to sit up or stand up and hates it when she's turned inward and can't see what's going on. What she plans on doing once she sits up is beyond me -- she usually ends up flopping over. Eventually she'll learn to think ahead a little. :)
My friends at work got her a Bumbo seat. She's starting to tolerate it better than she used to. At least now she doesn't fuss. I think she likes that she's sitting up like the rest of us. The other day she wouldn't let me put her down, so I put her in this and set her on the kitchen table so I could get some dishes done. She always seems to slide to one side or the other . . .
