Rachel Uchitel's Gift Registry -- I Need $300 Nipple Suckers

Rachel Uchitel ain't planning to be a full-time breast-feeder when her baby is born -- TMZ has learned, she's asking friends to buy her a $300 nipple pump instead ... on top of several other extremely expensive baby goodies.

Rachel -- who announced her pregnancy last night on Twitter -- posted a baby registry online recently, asking for a laundry list of newborn crap .... including the nipple pumps, a $500 high chair, a $300 car seat, TWO strollers ... one for $400, and one for $1000, and $300 cashmere bedding.

This kid's making out like a bandit -- like mother, like child.
