Dont know where you get your facts from.
My family gets together, e/o babysits their own children.
We all come to my mothers kitchen before pesach to help cook and bake while the children are in school.
We are not an exception as I know other families that do the same.
Since we all have KH large families, Pesach is the one time of year where we get togther and the cousins get to know eachother.
I am looking forward to being a part of the noise, the mess, and the cleanup.
