OMG She's Sitting Up!!!

Last weekend Grandma bought Jaclyn this Farm Animal Counting Book that makes all kinds of noises for her half birthday...yeah! Mommy and Daddy's FAVORITE!!!! LOL Jaclyn has decided that this is her favorite thing EVER and will sit with the book, completely satisfied, for half an hour at a time! I'm so glad she's taking an interest in books, but that's not the big news this week. Jaclyn's been working on propped sitting for awhile, but since we've introduced this book, she's been working on sitting up all by herself so she can hold and play with the book without Mommy and Daddy's help. We've been practicing this for the last couple of days and now I can even feed her avocado (her favorite food so far) while having her sit in front of me on the floor instead of having to use the high chair. She's also rolling all over the place now. If she wants to get from one place to another, (usually she's going for a toy) she does barrel rolls over and over again until she gets there. She still gets stuck once in awhile, but not for long. As exciting as all of this is, it's also making us VERY nervous for what comes next.... Did I mention I caught her on all fours in her crib recently?
Here's Jaclyn practicing her "Propped Sitting." She's working on moving herself from this position to sitting all the way up on her own. It takes a little while and usually some help from us, but once she's sitting up straight, she's pretty stable.

Her thinking face...we've been seeing this a lot lately as she is constantly exploring her surroundings and trying to figure them out now!
John and I are still trying to figure this one out. Every new toy she gets, she eventually decides that the tag is the most intriguing part. Go figure!
