So I am totally behind on my weekly updates. I will do week 21 today and week 22 tomorrow! :) Then I will be all caught up.
A 21 week old baby is a fully developed child that lacks the lung maturity to live outside the womb. From this point the child only needs to gain weight and lung maturity to be born. He is the size of a carrot. My sister and I went to the doctors this week and his heart rate is 140.
