Thump-Thump...Thump-Thump...

Baby is 4 weeks old today...6 weeks counting from the LMP. Today pregnancy.org tells us that the baby's heart should begin to beat today! Yesterday the inner ear formed, wonder if he/she/they can hear us yet?? Last week the embryo became 3 layers. The outer layer becomes the brain, nerves, and skin. The placenta becomes fully functional. The middle layer becomes the bones, muscles, blood vessels, heart, and sex organs. The inner layer becomes the stomach, liver, intestines, lungs, and urinary tract.
