My nephew and his wife recently had their second child, and they are following a well-worn path from the city to the suburbs.
Four years ago, childless and carless, they lived the urban life in the fashionable Washington, D.C., neighborhood of Cleveland Park. Child No. 1 pushed them four miles out, to the expensive inner Maryland suburb of Bethesda, where they bought a cozy two-bedroom condominium that had been converted from an apartment. Then, a couple of months ago, Child No. 2 pushed them another 12 miles farther out – beyond the Beltway – to Rockville, where they bought a four-bedroom, 2,200-square-foot house.
