if they are just tagging along and dont have to really get anything.. then maybe give them like.. $5 each (soudl be ok for 5 and 6 yr olds).. and say they can buy anything with it.. should keep them out of ure hair and from throwing tantrums... same thing with grocery stores.. my mom used to do taht with my kid sis... she was a good kid but would go crazy at grocery stores.. so she got a few dollars from mom and she could buy whatever .. :D
That is a good idea , why didn't I think of it . I will start using it immediately.
