Week 16

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

• All the joints of the foetus are working and the fingers and toes are all there and waving about.
• Toenails are just starting to form.
• The head still looks kind of oversized but the rest of the body is catching up.
• The downy foetal hair called lanugo has started to grow on the body. (Lanugo means fine wool in some ancient language). There are various opinions about what the lanugo might be for: it might help keep the foetus warm, or it might be an underfelt for the gooey stuff that eventually covers the baby. Or maybe the foetus is just trying to develop a fashion instinct!
