Spent 3 hours here with my 3 year old son. Great range of activities - everything was of interest to him, from the bubble activities to the preschool play area. Lots of attention to amenities such as family bathrooms and sinks for washing hands next to messy play areas. Easily worth multiple visits. The Au Bon Pain restaurant in the museum offers kids meals, which is not typical of this chain. Parking in the nearby lots is ~$10, but if you go on a Sunday, you can sometimes find free parking at the meters a few blocks away. Admission is a bit expensive, but is still a good value for the money.

I have a 4 yr old and a 1 yr old, and they both loved the Boston Children's museum. We went on a Monday afternoon, and it wasn't crowded at all. My 4yr old liked the Arthur room the best, and they have a infant/toddler room for kids under 3 that was great for my little one. If you aren't familiar with the area, make sure you have good directions, because we got lost for an hour trying to find the place.

LOVED IT! Visited with our children, both under 6 years of age, and they had a blast. Admission was very reasonable. We visited on a Sunday morning as soon as it opened and the crowds were fair - moderate.

Definitely one of the highlights of our trip for our youngsters, won hands down over the Aquarium.

Great!

This is a great interactive museum and one of the best deals I have ever seen. On Friday nights admission is only $1. There were three levels packed with fun and entertaining activities. The current music exhibit was one of our favorites, as were the art studio and workbench areas.
