Your baby this week
This week marks the end of your first trimester.
Your baby weighs now weighs slightly less than 14 grams and is about the size of a large tomato. Most of your baby's critical systems are fully formed and he/she is about to enter the growth and maturation stage, in which the organs and tissues will grow and develop rapidly.
In week 12 your baby begins to develop reflexes so if you poke your belly, you might feel your baby moving.
This week is the beginning of a critical time of brain development. There are two phases during a pregnancy where the baby’s brain goes rapid development; between 12 and 18 weeks and again between 24 and 36 weeks. During this time, it is especially important that you avoid being exposed to anything that could affect this development. Alcohol, tobacco, chemicals and even stress can affect the growth that is taking place inside your baby’s developing brain.
