Well, I've never been a mom before so sorry if it seemed like a silly question.
I took some suggestions. Bella went with me to PetSmart. We picked out two new toys, both with feathery material on them (her favorite), and got her a can of tuna and chicken wet food. I put it in her bowl and sang happy birthday to her, and she has been playing her new toys ever since she ate.
She was SO good in the store. I thought she'd be so skittish and try to get away. But no, she sat holding on to my shoulder while we shopped, and let cute little old ladies pet her. They talked about how "sweet" and "well-behaved" she was; of course, I was beaming like a proud mommy.
Thanks for all the ideas, I really appreciate the help!
HAPPY ONE YEAR OLD BIRTHDAY, BABY GIRL!
