How Big is Your Baby?

The brain and nervous system are rapidly maturing in the baby along with good sensory development. The protective covering of nerves, myelin, is forming this week to help in the development and proper functioning of the nervous system after birth. The fetal movements of the baby can be traced by ultrasound scan, so this time you can see your little one yawning, frowning or rolling. Your baby’s genitals will be formed by this week and if it is a girl, then the eggs will already be developing inside her body.

Mother’s Changing Body:
What to Expect


This week, you can feel your little sweet pea moving inside your tummy. You can sense your baby rolling, kicking, twisting etc., as slight flutters and finally you can feel that your pregnancy is real.

As the baby’s first movements are usually felt between week 18 and week 22, some women may not have experienced it yet, so do not panic; wait for a week or two and then consult your gynecologist.

You might not have a continuous good night’s rest due to uncomfortable pregnancy symptoms; relax your body through prenatal massages, yoga or aerobics during day time to sleep properly at night.

Pregnancy Tips for Week 18

  • This time, take your husband along with you for the ultrasound scan so that he can see and connect with the baby emotionally.
  • To avoid edema and backaches, try to relax in a straight posture at regular intervals. Keep your feet on an elevated foot rest to avoid further aches.
  • While getting up from bed, do not stand up too quickly. Try to get up gradually as it will balance your body from fainting.
  • Perform some simple calf stretches before going to bed to tolerate the leg cramps during the second trimester.
  • Walk regularly or involve yourself in routine fitness activities to avoid body pain and leg cramps.
