So I go to the mall with my kids. And I just let them money and they buy what they need and i help the little ones (7 and under).and they just get what they need And the stores they go to. So they put their bags in the kitchen and run off. I look at the clothes they get . The little ones just go to carters and the childrens place. I have four little ones Sammantha, Jessica, John,Lily.
