Recently I was informed of the stratospheres of baby strollers. (I live in Tribeca, the land of ex-model mommies and their nannies.) Here I had been thinking all along that Maclaren strollers were the cream of the crop, when I was kindly corrected by a girl-friend of mine that said, No, no, no, Bugaboos are the Rolls Royces of baby-dom. My bad. Now those new mommies-to-be have another ladder rung to climb. Word is that Little Marc Jacobs has collaborated with Bugaboo to create a limited edition Cameleon stroller with an all black frame and black on black “love Marc” print. Come November 26th, there will only be 15 available worldwide.  Now how’s that for a silver spoon?
