Week 23 of Pregnancy: Fetal Weight Gain

At eight inches and slightly over a pound, your baby is the size and shape of a small doll. You've probably heard your developing baby's heartbeat through a Doppler a number of times, but by now you can also hear it through a standard stethoscope. What a heart throb!

At eight inches and slightly over a pound, your baby is the size and shape of a small doll when you are 23 weeks pregnant. (But then, you already knew that you were carrying a living doll, didn't you?) This week marks the beginning of some serious weight gain. Your baby's weight in the next four weeks alone should double (and you may feel as though yours is too).

You have probably heard your developing baby's heartbeat through a Doppler a number of times already (though you never get tired of hearing it), but by now you can also hear it through a standard stethoscope. What a heart throb!

Your baby's skin is reddish in color now because of the developing blood vessels underneath (remember, the skin is very thin still). It also hangs loosely from his or her little body at this point. That's because the skin grows faster than the fat develops during fetal growth. But don't worry. By the time your baby is born, he or she will be pleasantly plump and filled out — from chubby cheeks to chubby toes.
