D.C. with a four year old?
 

We're following Dad on a short business trip with our son. What's the best destination with a four yr old?

We've never gone wrong with either the museum of natural history (especially all the dinosaurs) or the air and space museum. Even a 4 year old will get something out of both of those!

The Smithsonian's Postal Museum (next to Union Station) was a huge hit with my four-year old nephew, largely because it was all about moving the mail and little boys are usually crazy about transportation -- trains, pony express wagon, small airplane, trucks, etc. He also enjoyed using various means of transportation to get around, especially riding Metro backwards toward National Airport.<BR>(Of course, if you are coming from NYC, the subway would not be the adventure it was for a little boy from Kentucky.)

Visit the Old Postal Pavilion (Federal Triangle metro), and take the free tour up to the top of the clock tower &amp; look out. Small food court in the basement for some refreshments too.<BR><BR>Would a 4 y/o be too young to take on a paddleboat (human powered) ride? Located in Basin near Roul Wallemberg (sp?).

My kids enjoyed the DC Ducks. It was a fun way to see the sights and get an overview of the city. After taking you by the museums and monuments, the amphibious vehicles plunge into the Potomac river for a ride near the Jefferson Mem'l, the Reagan National airport and then back on land and back to Union Station. Our kids even got to drive the &quot;duck&quot;. 90 minutes of fun on a nice day! I think a four year old would enjoy that.

National Zoo is another good choice
