This week the air sacs in the baby's lungs will release a moist fatty substance called surfactant. It helps keep the air sacs inflated and prevents the lungs from collapsing when the baby starts to breathe after birth.
By now, almost all of the soft down that first covered the baby's skin will have disappeared.
Your baby could well have a whole head of hair already, but that is certainly not always the case. Neither does this offer any guarantee as to what his hair will look like in the future. Nevertheless, children born with very fine hair often also have thinner hair later in life.
Your uterus has now expanded so much that the top reaches halfway up your breastbone. You are probably feeling more and more tired.
And you could well be retaining water. You can tell by looking at your feet and ankles. Make sure you get enough rest. Have a cold foot bath and put your feet up, literally. Lie down with your feet up high against the wall, or sit with your legs well supported and your feet higher than your hips. If none of this helps then talk to your midwife or obstetrician, who will check your blood pressure.
Your check-ups will be once a fortnight from now on.
