Pregnancy Week 3: Baby Growth
Your baby is now an embryo around 1mm long, only the size of a little poppy seed. This phase of your pregnancy is the most critical period of development and lasts for about 10 weeks. Your baby’s organs are beginning to develop and some will even start to function. The stage where your baby’s precious body is taking form - sigh!
The amniotic sac (the nest that will hold your baby safe) is now formed and filled with liquid. This cushions your baby and keeps them protected from the world’s external forces.
Your baby’s nervous system (their brain and spine) will start to develop during this week, so make sure you are taking folic acid supplements to prevent spinal cord defects. After all, you want to lay a strong foundation for your child's life ahead!
