I have a 10 month old son and 2-1/2 year old twin girls. My kids love: story time at the library, browsing the library, visiting the animals at pet stores, playing with the lego and train tables at Barnes & Noble (most book stores also have story time), play area at the mall, walking around Toys R Us, aquarium, children's museum and Sam's Club - they love the samples :) I also belong to a meetup group and attend a playdate once a week.
