Week 20

Check out what how your baby is developing this week: -

• The foetus puts on more muscle and tests it out by moving around.
• One book says your baby is as heavy as 'a medium-sized Spanish onion.
• The skin's sebaceous glands (needed, of course, to make pimples later) become active and make the oily stuff called vernix caseosa that covers the skin. It's the foetus's do-it-yourself wetsuit made, disgustingly enough, of fatty material and dead skin cells. Vernix caseosa waterproofs the skin against the amniotic fluid, and protects the foetus from scrapes when it bangs into the wall of the uterus.
