23 Weeks

Your pregnancy: 23 weeks

How your baby's growing:Your baby is more than 11 inches long and weighs just over a pound (about as much as a large mango). His skin is red and wrinkled. Blood vessels in his lungs are developing to prepare him for breathing. He can swallow, but he normally won't pass his first stool (called meconium) until after birth. Loud noises heard often in utero — such as your dog barking or the roar of a vacuum cleaner — probably won't faze your baby when he hears them outside the womb.
