We just got back from a long shopping trip. It was Tia's first that we used her carrier for. In petsmart, I held her (she was scared to be on the floor

) and in payless and Target she went in her bag. BAD IDEA, she threw up about four times - first in her bag at Target, then on the drive home. I feel so awful for her. She seems to be okay now, just resting pretty well. She's had some water. My husband thinks it was the bag (the movement, etc) - I think it may have just been too much too soon (she's 5 months, but this was her first BIG outing). I'm just really concerned that I've hurt her or damaged her. Any words of wisdom?
