Most of your baby's systems are now fully formed! They will still need time to grow and mature, but it's an exciting step in a great direction. Can you imagine your baby flexing his bicep? Okay... maybe he's not a weightlifter just yet, but your baby has developed the ability to use his reflexes. This week he will learn how to wiggle his fingers, curl his toes, blink his eyes, and best yet, pout his lips. (I don't know about you, but I can't wait for a slobbery baby kiss!) Your baby is now officially on the move! You might not be able to feel it yet, but he is starting to move around. If you press on your abdomen, your little one will shift in response. Do you want to make your heart skip a beat (theoretically, of course!)? Well, I've got wonderful news for you! This week you'll likely be able to hear your baby's fetal heartbeat on an external Doppler device. I promise... it's one of the most beautiful sounds in the world.
