Another week, another mini milestone and one step closer to being a mum!
This week there is an incredible development in their lungs as they will be able to inflate properly from now onwards. Their lungs will start producing surfactant from this week preventing them from collapsing as they start breathing smoothly after delivery.
Their ears will be completely developed from the inside as well as outside and they can now hear your voice as well as other familiar voices from outside the womb.
Their skin is pink in colour instead of red at this point and they have well developed finger nails.
Their bones are growing stronger and will require more calcium than ever at this stage to grow well.
They receive all their nutrients through the placenta and the placental blood flow enables them to make urine, which they pee about half a litre every day! which they swallow in the form of amniotic fluid which is now replaced a few times daily.
The amniotic fluid needs to be measured as a routine to detect any problems. If there is too much fluid in the amniotic sac it could indicate that they are not swallowing properly or having a gastrointestinal difficulty. If there is less fluid in the amniotic sac it could indicate that they are not urinating enough or has a problem with their kidneys.
Their arms, legs and body continue to fill out this week – and they are finally proportional in size to their head and are now looking more like a newborn.
Their bone marrow has taken over from the liver in producing red blood cells. Soon we can wonder what your they are wishing for – brain scans have shown that babies have periods of dream sleep around month eight.
7 weeks and 2 days to c-section day!
