The baby’s lungs cannot start functioning properly until after the birth. That’s why they take longer to develop than the other organs.

The protective mechanism that prevents the air sacs in the lungs from collapsing or sticking together is developed at a later stage in the pregnancy. That’s why premature babies can have difficulties breathing.

Treat yourself to regular breaks and avoid standing while you are working whenever possible. That way, you can reduce the strain on the ligaments of the uterus, which are now being increasingly stretched. And remember: you should not lift or carry anything weighing more than 5 kilos. In everyday life this takes discipline – particularly if you already have a small child.

During weeks 20 to 24 of pregnancy your baby is about the size of a papaya.
