One-third of this pregnancy is over! Baby Chris has entered the second trimester, and this week, his or her weight has increased about 58%. He or she is now about the size of a lemon.
The bladder is developing smooth muscle cells, the taste buds are maturing, and the arms have lengthened. Fingernails and toenails are forming. Baby Chris's nervous system is sensitive enough to respond to light touch in most places. Baby Chris can squint, frown, grimace, suck, and chew.
