The baby's head now only accounts for half of the length of the body and the arms are folded across the chest. Reflexes are developing – the baby starts to swallow and suck. Your baby can already suck its thumb. For the mother this is the period when sickness can get bad, but it is still a good idea only to tell your nearest and dearest that you are pregnant.
By the end of this month the baby will already be around 6 centimetres long from head to rump (the size of a lime). The embryo has become a foetus and continues to grow very fast. The basic physical structure is in place but there will still be a lot of development in the months to come. The tiny heart already has four chambers and the beginnings of 20 tiny teeth are ready in the jaws. The eyes have also formed but are covered by the eyelids, which are currently fused together. The arms are now folded across the chest and the legs have grown long enough to be crossed. Reflexes are also starting to appear.
If we could look into the womb, would already see the occasional smile on the baby's face. The baby can also frown and suck its thumb.
Hello mood swings! One moment you are full of optimism, and the next you are seized by fear and despair. This is perfectly normal. A heightened sense of smell is another frequent phenomenon, which can unfortunately contribute to feelings of nausea. Although it is difficult to keep good news a secret, it is still a good idea to wait until the end of the first trimester, when the most critical period of the baby's development is behind you, before you tell people – apart from those closest to you – about your pregnancy.
What were your feelings during the first scan? Write it in your diary!
The growth of the foetus in this period is so fast that the length of the body can double in a single week. The baby's intestinal development is also very rapid. The intestines develop in the umbilical cord and slowly move into the baby's abdominal cavity, where rapid growth ensures that there is enough room.
