In the eleventh week, your baby is developing the facial characteristics that will make them unique (and oh, so cute!). This is thanks to the increasing growth of bones and cartilage that kicked off at greater speed during Week 10.  

So, your little one now has: 

• Hands and feet that are no longer webbed and are growing nails 

• Ears closer to their final destination and shape 

• Open nasal passages (from the nostrils to the nasal cavity) 

In the tenth week, you are in your third month of pregnancy and your baby has passed on from being an embryo to a fetus! Your little bud will continue developing during the fetal stage up until birth. 

So, what’s different now? For starters, they no longer look like a tadpole – distinct human features are becoming more and more apparent. This is mainly due to the development of bones and cartilage. Your baby now has tiny arms with elbows that they can flex, and the legs are growing small indentations that will become knees and ankles. 

This is your baby’s last week as an embryo before entering the fetal stage. 

Your little one is looking more and more like an actual baby! The tail at the end of the spinal cord has nearly disappeared. 

The face is taking shape, having already a mouth and a tongue with taste buds, as well as tiny teeth in the gums. The eyes are now bigger and slightly pigmented. 

Moreover, all of your baby’s essential organs have begun developing. These are: 

• Heart 

• Brain 

• Lungs 

• Liver 

• Kidney 

Your baby is inside an amniotic sac. Within that lies the yolk sac, whose primary function is to provide nourishment while the placenta is developing. The yolk sac will disappear around the end of your first trimester. Meanwhile, the placenta is undergoing some structures that will attach it to your womb.  

As for your baby’s growth, they are currently about 1.6 cm long, or 0.63 inches. In fact, the little one is growing very fast, approximately three to four-quarters of an inch. By next week, they will have doubled in size – cool, right? 

By this week, your baby is now about 1 cm long (0.4 inches), approximately 1,000 times bigger than it was when conceived!  

The little one’s size is measured with the “crown-rump length” (CRL) unit – as in, the distance from the top of their head (crown) to the bottom of their torso (rump). The CRL is used in the embryonic stage and can be detected via ultrasound imagery to estimate the gestational age. 

By week 6, your baby’s face is beginning to take form, particularly the cheeks, jaw, and chin. The ears are also starting to develop, but they’re like little holes that will eventually have the cartilage for the lobes.
