We have been members of Brooklyn Children's since my son learned to walk. Every year he discovers new favorite things to do when we go. It's by far the best thing to do with little kids on a rainy or snowy day in Brooklyn... it will keep them happy for hours and hours without fail. The cafeteria serves a variety kid-friendly food and has some packaged kosher options and snack machines as well. A bit overpriced as can be expected but not exorbitant. The only drawback is the lack of parking, amplified by the fact that it's a bit of a sketchy neighborhood. If you come by car, either come early or bring an extra adult to park while you take the kids inside. By train, I recommend taking the number 3 or 4 train rather than the A or C if you have a choice. Generally speaking it's best to go earlier in the day, especially in bad weather, as it does get very crowded and some of the exhibits can become fairly ravaged by the afternoon. If you have an under-5 that likes water, bring an extra shirt to change into as there is a great but messy water play area. Has reciprocal membership with ASTM and ACM.
