Your baby weighs roughly 2.5 pounds (1.15 kg) and measure about 15 inches (38 cm) long. Sensory organs are well developed and he is beginning to regulate his own temperature. The bone marrow is now completely in charge of producing red blood cells as well.
Fluttering, the kicking sensation you feel in your belly, has become more active as your baby kicks and punches more. Make sure that your baby moves at least 10 times an hour. If he moves any less than that, make sure to talk to your health care provider. His lungs are developed enough to breathe air and he is urinating about a half liter of urine into the amniotic fluid daily.
