Don't know where you are, but our Catholic parish is packed to the rafters with babies, young children, teenagers, and young parents enthusiastically presenting the parish with more. We middle-aged former ECUSAers brought a few teenagers with us, too. There were nearly 100 kids in the last confirmation class. They had to stand them on the chancel steps turned sideways to get them all in the official photo with the Archbishop.
Our kids' choir is jumping and the youth group has outgrown two different meeting rooms.
Maybe you need to look into outreach for your parish?
