8 Weeks – 42 Days after Conception

It is Thursday and time for the glorious weekly update!

8 WEEKS!!!

Your baby’s head is quite big, due to the rapid growth of the brain. The upper limbs resemble paddles. In the next few days foot plates, with the beginnings of toe rays, will appear. The external ears are present. Your baby is now 13 to 16mm long – about the size of a cherry. This is a big week, as gonads differentiate, becoming either testes or ovaries. Also, your little one begins to move spontaneously this week, though you won’t feel it yet.

Your baby’s face is becoming recognisably human. Their cheeks, mouth, lips and chin are more defined, and they now have nasal passages that create the tip of their nose. Your baby develops eyelids this week, which will remain fused and closed until they reach 24 weeks of pregnancy.
The internal and external parts of your baby’s ears begin to form, including their middle ear which is responsible for their hearing and balance. However, your baby will not be able to hear until they are somewhere between 19 to 24 weeks. Your baby now has immature taste buds on their tongue and under their smooth, translucent skin many tiny blood vessels can be seen networking through their body.

    I hope your baby isn’t scared of the dark – it looks very dark in there. I’m amazed that so much happens so early – I guess I didn’t think that much of it.

      Oh yes, by 13 weeks, most of the baby’s organs will be formed. It is amazing stuff!
