V.H.
I'm a mom of 2 children: 6 and 3 and I've hired Joby & Sox who are a husband & wife clown-team. They are great and keep the kids entertained with Face painting, magic, baloon animals and more. My parties too have had a age gap and they've all enjoyed their entertainment.
I highly recommend them and I believe they perform regularly at the McDonalds in Westport. They can be found in the yellowpages or try google.
