Fetal Development Week by Week – Week 10

Your baby is now about 1 ½ inches long and weighs about 5 grams, it resembles the shape and size of a peapod.  Hormones may be raging for you at this point, and you may feel sad and tearful one moment and happy the next.  This emotional roller coaster is normal and it will even out some over the next few weeks.

Even though it is very difficult to discern the sex of your baby by ultrasound at this point, the genitals are forming.  Your baby’s brain is forming 250,000 neurons every minute.  Brain development is very rapid at this time. 

The head is upright and your baby can turn their head, open their mouth, smile and practice breathing.  The outer ear is completely formed and the inner ear is nearly complete.  The intestines begin moving from the umbilical cord to the abdomen and all the vital organs are formed and starting to work together.  The lungs are continuing to develop.

The arms and legs are well formed and fingers and toes are not webbed any longer.  All of your baby’s joints are formed, so they can bend their fingers and make a fist.  The can kick and curl up their toes.

If you haven’t already done so, now is the time to make a decision about CVS testing.
