Among the miracles of parenthood is that everyone makes its through sane. Gear up at Giggle, a tot shop equipped with a stroller parking lot and kiddie goods cherry-picked for urban life. Clueless shoppers--or those just addled by sleep deprivation--can get guidance from essential-tools checklists provided for expectant parents. Among the options are a Stokke Xplory stroller ($950), which converts to navigate stairs; an ultracompact Great Expectations changing pad ($28); and vibrant Dwellbaby bedding sets ($270). Sadly, what new moms and dads most crave--an hour of peace and quiet--is not among the offerings.
