As a (relatively) new dad, I would find this very useful. There doesn't seem to be a central repository of such places and the ones in my city (Cincinnati) are really badly organized, maintained, ect...

There is room in OpenStreetMap for this sort of data. Parks and playgrounds are already frequently marked (along with stuff like museums), and there are at least a few people trying to figure out things like changing tables.

I guess it would take a while before people were chasing details like kids menus.

There is Wow dad, and there is mum version called Wow Mum (maybe Wow Mom). https://play.google.com/store/apps/details?id=co.wowdad.ui

It really bugs me that this is restricted to ireland, UK and USA. :(

If anybody is interested in working on something like this let me know :)

We have an almost-ready app for finding bathrooms nearby - think Yelp for bathrooms. Adding support for baby services would be very trivial.

For some reason I like this idea, not sure why but seems like something that could help my wife immensely as well as other mothers.
