There are lots of us over 35 with little ones. Not sure if you are looking for a mom's group but I belong to a great one with many of the moms are over the age of 35. There is an infant playgroup as well as activities for all ages. Once a month we do Mom's Nights Out. It is a fun group of mama's going through the same thing as the next.
