I know it is a hike for you, but Betty's Fun Center in Aston, PA is GREAT for the very little ones. They have a whole section gated off for kids under 5 and they just renovated and added a bunch of new "soft play" items for the under 2 crowd.www.bettesfuncenter.com We were there this past Wed. and there must have been about 6-7 little kids under the age of 2.
They are $3 on Wed. for all day play. If you google you might be able to find some things like that closer to you.
Hope this helps!
