Though not in any way intended as a children's museum, this might be the one museum which would hold a child's interest. There's much that's bright and playful about its exhibits; the child in me enjoyed it, despite it being my 3rd museum of the day.
For an entry fee of $60MX (about $3.30US), the Museo de Arte Popular certainly gives you your money's worth. Spread over 4 floors, the sheer volume of objects on display amounts to a visual buffet.
If you enjoy looking at 3-dimensional arts and crafts as opposed to a framed, hanging 2-dimensional artwork, this is your place. From the bright, oversized creatures one would see in parades to paintings on pinheads, viewed through a magnifying glass, I can almost guarantee that your attention span will wane before you've taken in everything on display here. But skip it at your own peril, as what's on display here is not what you'll see at any other museum in town.
Museo de Arte Popular also has an interesting gift shop.
This is an immaculate and modern museum one block away from Alameda Central (the park that houses Palacios de Bellas Artes). If your attention span hasn't yet waned, it's worth about 1 hour of your time and if you come with children there's bound to be several things which capture their fancy.
