Haven't had time to catch up properly but I couldn't let this ridiculous statement slide.
Of course an 8 week old foetus is a baby. There is a lot of development taking place (various sources):
From weeks 6 to 10, your developing baby will quadruple in size and go through dramatic changes in appearance.
The baby is now around 16mm long, which is about the size of a raspberry.
Around now, the embryo becomes a "foetus", which means offspring in Latin.
Baby has now formed just about everything an adult has: bones, muscles, fingers, toes, a cute button nose–all of it! Believe it or not, they even start to get some eye colour. Fun fact: baby's taste buds are now forming, gearing up for their first meals. It’s early still, but there’s a lot of development happening.
The tiny head has started to uncurl a bit.
The eyes and nose are visible. There are little mounds where the shell of their ears will grow and their eyes are now more obvious, with eyelid folds partially covering them. This week the retinas have begun to form.
Even though you can't yet feel it, baby's tiny trunk and limb buds are now twitching and making spontaneous movements.
Your baby’s body is like a tiny jumping bean, moving in fits and starts.
your baby's lower limb buds take on the shape of paddles.
By 8 weeks, they will have shoulders and elbows, making the upper limbs project forwards.
Nerve cells in your baby's brain are branching out to form early neural pathways. The part of the brain responsible for their sense of smell is also taking shape.
The inner ear and the tongue are developing, and the roof of the mouth is coming together with the upper jaw.
There are hands at the end of their arm buds, and fingers are starting to grow.
The arms and legs are made of cartilage at this stage.
Their reproductive organs are also developing, but it’s too early to tell whether the baby is a boy or a girl.
The embryonic tail is almost gone, shrinking back to form the tailbone (coccyx).
By just 12 weeks, the baby is fully formed. NHS - All the organs, muscles, limbs and bones are in place, and the sex organs are well developed. From now on, the baby has to grow and mature.
