Your baby's getting big. He weighs a tad over 5 pounds (think bag of sugar) and is just over 18 inches long from head to heel. Of course, he's still curled up inside you: It's getting so snug in your womb that your baby isn't really floating anymore and he isn't likely to be doing somersaults. But tighter quarters don't mean less frequent movement; your baby should still be kicking at the same rate he always has. If you notice a decrease, call your health care provider. Your baby's kidneys are fully developed now, and his liver can process some waste products. Most of his basic physical development is now complete the next few weeks are all about putting on weight.
It is actually getting heavy to walk around with! 40 pounds, can you believe it? The ladies at work all tell me I look thin, and that's it is all baby-- I could kiss them when they tell me that!
