Buy Buy Baby (917) 344-1555 - 270 SEVENTH AVENUE (25TH AND 26TH)
While not on the Upper East Side, Buy Buy Baby in the west 20s offers the greatest selection of almost every baby need you could think of. This is where most NYC moms have their registry. One perk is their 10% completion discount which they send you prior to your due date so you could finish up your purchasing before the baby arrives. From furniture to strollers, to car seats to diapers to formula...this superstore has a poshier selection than Babies R Us.
