18 Weeks Pregnant

Baby Develops Fat For Warmth

This could turn out to be quite a momentous week for many pregnant moms. Why so? If you pay attention to your stomach, you could feel faint baby kicks.

18th week is normally the time when most first-time mothers begin to recognise the baby’s punches and kicks. If it’s your second or subsequent pregnancy, you would have probably felt the movements a little earlier.

Most mothers describe the kick to be similar to the fluttering of a butterfly. Some say it feels like bubbles popping. Others think it’s a weird ticklish feeling. You would probably be able to sense it better when you are resting and less distracted by other things.

How your baby is growing

  • Baby can yawn, swallow, hiccup and suck his thumb.
  • Baby’s movements are getting more intense, as baby begins to roll, turn, twist, kick and punch.
  • The nervous system is making rapid advancements. The nerves are now covered with a substance called myelin which helps in the rapid transfer of messages from one nerve cell to another.
  • Your baby is now covered with a white, waxy substance called vernix caseosa, which helps prevent delicate skin from becoming chapped or scratched.
  • Premature babies may be covered in this cheesy coating at delivery.
  • This week also brings the development of brown fat, which will help keep your baby warm after birth. During the last trimester, your baby will add more layers of fat for warmth and protection.
