22nd week of pregnancy

  • Biparietal diameter of foetus: 52 to 62 mm
  • Weight of foetus: approx. 500 g

Your baby is still quite thin, but slowly gains in weight and becomes rounder. As the body has been growing faster than the head, the child’s proportions start looking more balanced. The brain grows and develops cerebral convolutions.


In ultra sound images one can often see the baby sucking its thumb. This is a very important exercise for training the sucking reflex in order for the baby to have enough strength for breast-feeding. Sometimes it has the hiccups, which you can feel as small rhythmic twitches in the belly.


The foetus is rather active for some hours each day. If you lie down quietly, perhaps the father may be able to feel the kicking of his baby through the abdominal wall.
