15w 0d - "Pason" This Week

• Fine hair called lanugo covers your baby, who now measures about 4.3 to 4.6 inches (10.8 to 11.6cm) from crown to rump and weighs about 2.8 ounces (80g).
• Fingernails are well formed and the arms and legs may be seen moving on an ultrasound. Your baby already has his own unique fingerprint pattern!
• Your baby can hold his head erect and he can also make faces with his slightly developed facial muscles. Your baby may practice squinting, frowning and opening and closing his mouth.
• Your baby's bones have enough calcium deposits to show on an X-ray. If your baby is female, her ovaries will be in place in her pelvis and more than five million ova (some of which may be fertilized to become your own grandchildren in another generation!) have formed.
