At 37th week, the baby weighs about 6.5 pounds. This week, the baby is busy simulating breathing by inhaling and exhaling amniotic fluid, sucking on his or her thumb, blinking and pivoting from side to side. Your baby's head (which, by the way, is still growing) will, at birth, be the same size circumference as his or her hips, abdomen and shoulders.
Diet and exercise go hand in hand so keep in mind not to even miss one day of some sort of exercise in order for your pregnancy to be fruitful.
