from Pregnancy Weekly:
“Your baby is now about 16.7 inches from head to toe, and weighs about 2.7 pounds. He or she continues to be active and grow; however, you may be feeling fewer kicks and punches. This is because even though your baby is getting larger and stronger, he or she also has less space in which to gain momentum for these movements. Your baby’s blood is now being produced from the stem cells in its bone marrow.”
P.S. It is not true that I am feeling less kicks and punches. In fact, the baby is as active as ever!
