I would think about if she can keep up with you and not get lost. If something catches her eye she might stop to look while you're headed to grab something before anyone else gets it and then she gets lost. When I was young I got lost in the mall on black friday...it was really scary for me. I just got swept up in the crowds and when I turned around my mom was gone.
we get it off as part of the thanksgiving holiday but in other jobs i've had i've taken a vacation day! i've only had to work once and i went out shopping before work and talked someone into sharing my shift so i could leave early too!
