Never ever ever never leave your baby in the car! It is not worth it, It only takes 1 second for someone to steal her.
I agree with the others take her in with you, or make her a little area at your house! If you did leave her in the car, you know you would be stressed, looking in on her, checking your car..You wouldn't be able to enjoy yourself bc you would be stressed about her..
Im sure also someone that goes with you, would love to hold her while you are trying on dresses
So she can be part of the fun!!
