33 weeks

Weekly update from parenting.com:
Your little one is almost 4 ½ pounds and is gaining as much as eight ounces a week. She continues to sprout like a reed, her arms and legs perfectly proportioned to the rest of her body. She measures a total of 19 ½ inches and has little room to wiggle, but she's still quite active, even if it means she has to squirm around most of the time.
