With your pregnancy at 11 weeks, fingers and toes are separate and the baby can move them, even perhaps being able to clench his or her fist. The beginnings of teeth are forming under the gums, and the bones are starting to harden. A special layer of skin is growing on the toes and fingers, which will eventually become nails.
Your baby's heart beats very fast, about twice the rate of its mother. It can be seen on an ultrasound scan or heard using a Doppler scan (a type of ultrasound that measures the flow of blood). You might be offered a nuchal fold translucency test. This measures the amount of fluid between two layers of skin behind your baby's neck, and is another test for Down's syndrome. Like CVS testing, you're usually only recommended to have this test if you're particularly at risk of having a baby with a serious inherited condition.
Calcium is an important part of your pregnancy diet, as your baby needs it to form healthy bones and teeth. It can be found in dairy products, broccoli, wholegrain cereals, sardines and sesame seeds. Cheese is a good source of calcium but remember that you should avoid soft and blue veined cheese, such as Camembert, Brie and Stilton.
