391 Four months pregnant

Chen Lihua is now four months pregnant, and her baby bump was starting to become noticeable. She had a slight baby bump that appeared on her abdomen.

The size of her baby should be as big as an avocado, the weight ranging from 0.09-0.11 kg and 4-5 inches in length.

Chen Lihua got a newsletter, but more like an Email from the doctor, filling her in on her baby's development.

"Your baby's eyes are making small side-to-side movements this week and can perceive some light, even though they're still closed."

"That thumb-sucking habit of many newborns may have already begun. At 16 weeks, babies may be able to make sucking motions."

"Baby-to-be's circulatory system is now up and (beginning) to run. Her heart can pump about 25 quarts of blood a day."
