We've progressed with the stroller also. She's bored being in the infant carrier/car seat, and has moved on to sitting in the actual stroller. We walked around the mall yesterday, and she had a blast looking at everything. (Much more fun than having to stare at just me while she was in the infant seat). Since she had so much fun, I decided to go shopping again today...stictly for her benefit!
She also decided to sit up on her own. I put her on all fours, left the room and came back to find her sitting up! It's hard to believe that six months ago she was just taking her first breath and now look at all she can do. She is such a blessing!
