Please Touch Museum

Anybody ever been? We're heading to Philly for a daytrip and have a few hours to spare.

DD is 13 months old and wasn't sure if it would be worth it to take her. She can't walk on her own yet, if that matters.

If not there, any other places that would be good for infants/toddlers in the area that we could do for 3-4 hours?

We were just there on Sunday. DS is 14 months and just started walking so there was more for him to do, ie the Alice in Wonderland area has fun mirrors.
For a crawler there is a small area that has a slide like an indoor playground. I'm sorry to say there is not much for her if she can't walk. There is water play but you have to stand. If she can hang on to the side of the wall she can play but even then the rail is high so she might not be able to reach.
There are plenty of places where you can put her down and take pictures. There is also a carousel.
They weren't strict on the age thing. Just tell them she's 11 months so you don't have to pay for admissions for her.
