At 23 weeks, Owen is around 8 inches from the top of his head to the bottom of the buttocks (known as the crown-rump length). His height is over 11 inches from the top of the head to the heel (crown-heel length).1 This week, he weighs approximately 20 ounces or 1 pound 4 ounces (565 grams).
Activity
Owen is building more muscle and getting stronger and is very active. We can see his kicks already!
Brain Growth
His brain is developing very quickly during this time.4
Eyes
Owen can respond to light as early as 23 weeks.5 (If you shine a flashlight on your belly, your baby may react and move.) He reacts to our touch as well!
Fingernails
Owen’s fingernails now reach the tips of the fingers.3
Survival Outside the Womb
It is rare for babies born before 23 weeks to survive. However, extremely premature babies born during the 23rd week of pregnancy do have a chance of surviving. Babies born this early are still not ready for life outside the womb. They require a high level of specialized care in a neonatal intensive care unit (NICU). Research shows that in developed countries, between 23% and 27% of babies born at 23 weeks survive to go home with their family.6
