18 Weeks Pregnant – What to Expect Your 18th Week of Pregnancy

Your baby may be large enough in week 18 of your pregnancy (or anytime in the next few weeks) for you to feel him twisting, rolling, kicking and punching his way around the womb!

This is a week of exciting change and development for your baby! Their eyes may be able to detect light, and their nervous system is further developing. Find out what to expect as Heidi Murkoff talks you through this wonderful week!

At 18 weeks, your little chick is about the same size as the chicken breast on your dinner plate, about five inches long and five ounces in weight.

But don’t let his small size fool you. There are big goings-on in that little body of his this week. Meconium, your baby’s first poop, is slowly starting to accumulate in his bowels. If your baby’s a boy, his prostate gland is forming. And both girl and boy babies now officially sport finger and toe prints. These tiny swirls and wrinkles mark your baby as uniquely himself from here on out, though there’s probably little need to tell you how especially unique your baby is!

Under major construction now is your baby’s nervous system. That’s the network that coordinates your cutie’s every move. Right now your baby’s brain, spinal cord, and nerves get a boost from myelin, a substance that coats the nerves and speeds up the time it takes for messages to travel between nerve cells. Myelin also helps baby’s nerves form more complex connections, enabling your teeny mover and shaker to perfect more intricate moves such as sucking a thumb, clasping hands, and curling his fingers around the umbilical cord.

And guess what, momma! Somebody’s listening to you. Baby’s ears have arrived at their final destination – the sides of his head – and the tiny bones inside the inner ear have hardened, allowing your baby to hear some sounds, including the sweet sound of your voice! Now hear this. Thanks to all the time they spend listening to it in utero, studies show that babies are able to identify their momma’s voice right after birth. Keep that in mind the next time you serenade your womb with your lullabies – or rock out in the shower. Your little one is all ears!

My buddy and her husband have been looking to have a child for 3 years. Their advisors have not been able to assist them as well. My friend decided to follow this guide and after months of sticking to the plan, her conception was successful. You can learn about this method more by getting to Google. I remembered its name is Sofia Goρazna
take care
