I always thought in order to make your party kid friendly, you had to loose some of beauty. Devout part of your party to the kids and loose out on the aesthetically pleasing part. My mom and aunt did a beautiful job of pulling together my brother's wedding dinner and they made it kid friendly too.
My aunt pulled together these gorgeous center pieces on half cloth/ half paper tablecloths. Then they left boxes of crayons on the paper tablecloths. The kids has a blast coloring and playing and they even stayed in their seats because their attention was on what was right in front of them.
