We've collected NYC's best drop-in tot times at indoor playgrounds, toddler classes, singalongs, and other favorite events where children preschool age and younger (along with their caregivers) can enjoy open play, activities, socialization and learning opportunities that cater specifically to the youngest New Yorkers. Check out your local library for more drop-in playtimes, as well as our list of non-library story times for even more toddler fun!
