Our baby doesn't have much room to maneuver now that she's over 18 inches long and tips the scales at 5 1/4 pounds (pick up a honeydew melon). Because it's so snug in my womb, she isn't likely to be doing somersaults anymore, but the number of times she kicks should remain about the same. Her kidneys are fully developed now, and her liver can process some waste products. Most of her basic physical development is now complete — she'll spend the next few weeks putting on weight.
