Though your baby’s nervous system has been developing ever since the first few weeks of conception, this fascinating body system is undergoing major development at this week.

This is because myelin is starting to form around the nerves. This cover protects your baby’s nerves and plays a vital role in neural transmission. Further, they speed up the messages sent from neuron to neuron. Without myelin, many congenital defects may develop.

Myelin forms until about 12 months of age. Remember that the five senses - sight, hearing, taste, olfaction and touch - are part of the nervous system, too. Even after birth, these senses still undergo fast development.

Indeed, your baby’s hearing inside the womb is growing more complex by the day as your little one grows more observant to outside noises. The nervous system does an incredible job, doesn’t it?
