Head to heels, your baby now measures about 13 1/2 inches. Her weight — a pound and a half — isn’t much more than an average rutabaga, but she’s beginning to exchange her long, lean look for some baby fat. As she does, her wrinkled skin will begin to smooth out and she’ll start to look more and more like a newborn. She’s also growing more hair — and if you could see it, you’d now be able to discern its color and texture.

Week Twenty Five: Exploration continues

You are 25 weeks pregnant. (fetal age 23 weeks)

  • The unborn child is 34 cm in length and weighs almost 690 grams.
  • Baby is around 13.5 inches in length and weighs 1 and half pounds.
  • Bones are becoming solid, hands are now fully developed.
  • The brain is growing rapidly, the brain cells are starting to mature.
  • The sexual organs are fully developed.
    Baby is now pretty well built portion wise even though it still has little body fat and its skin is thin. The structures of the spine begin to form — All 33 rings, 150 joints and 1000 ligaments. The tiny brain is growing rapidly, and the baby is starting to fill the space in your uterus. The uterus is now about the size of a soccer ball and mom looks pregnant.

    Your baby’s hands are now fully developed, although some of the nerve connections to the hands have a long way to go. Dexterity is improving. Your baby can make a fist and clasp objects placed in palm. Exploring the structures inside your uterus may have become baby’s prime entertainment. Fascinated by the amount of tactile stimulation a fetus gives itself; it touches a hand to the face, one hand to the other hand, clasps its feet, touches its foot to its leg, its hand to its umbilical cord.

    Blood vessels of the lungs develop. Your baby’s nostrils begin to open. The nerves around the mouth and lip area are showing more sensitivity now. Their swallowing reflexes are developing. Baby can hear sounds outside the womb and the brain cells are starting to mature also. Already it can learn and remember and can recognise its mother and fathers voice. The inner ear bones have hardened so hearing is more acute. Baby may hear your partner’s voice more easily than yours, as baby is sensitive to a deeper pitch.

    Babies born at 25 weeks of pregnancy have about a 50% chance of survival.

    The cortex (outer layer) of your baby’s brain is developing into layers, paving the way for sophisticated brain activity like thinking, feeling and planning in years to come. Her eyes are fully functional, and she may blink as a reflex reaction to a loud or sudden noise. Studies have also shown that an unborn baby will turn her head if a light is shone onto the mom’s abdomen, proving that her optic nerve is now working.

    Your baby’s lungs are maturing by the day and she’s making breathing motions, although if she were born before 37 weeks, it’s likely she would need help to breathe. Her sense of smell is developing, too. One study showed that babies whose moms eat lots of garlic respond more strongly to the smell after the birth. Tiny blood vessels called capillaries are now developing beneath the surface of your baby’s skin, which will give her skin its pink color.
