Happy 7 Month, Eliza!!! My baby sister turns 7 months old today, and here are some of her most recent snapshots. I still like her okay, but she's starting to be naughty and take my toys away from me, and then getting mad if I do the same thing to her. I'm hoping by the time she turns 8 months old she'll learn some manners, and realize that everything is mine until I either say it is hers, or it is broken.
