My Idea for an Interactive Website

If I were to create an interactive web page I would try to develop some kind of activity page for children. The issue I have with my 14 month old is trying to find classes for her to take and things to keep her busy, challenged and interacting with other children her age. If there was a website that listed not only all of the activities in the area but the age of the children attending the classes and how many children attended. Maybe have someone updating it as the children entered the class so someone could go onto this website, see a class they might like their child to attend and look to see what other children are there and what their ages are. I wouldn't want to get all the way to a music class for my daughter and find out there was only one other child there in the class, kind of a waste of time.
