Your baby gains about 6 oz this week as the body begins to fill out. This weight is in muscle, bone mass and the growing organs and tissues. The weight could top at 1 1/3 lbs by the end of this week. The fetus will also begin to produce white blood cells, which will help combat infections and diseases after birth.
From this week on, you may be able to feel your baby's hiccups in the womb. The baby will respond to certain noises and sounds, and your partner will be able to hear a heartbeat if he puts an ear to your belly.
Traveling this week for business...Last time ever until the kid comes out, hopefully!
