Your baby is starting to be able to hear! Though it might not be very clear, the first sounds to be heard will be your heartbeat and blood moving through the umbilical cord.
The fifth month is also the start of the critical period where your baby's intellectual development can be influenced through prenatal stimulation.
The swirls and creases of fingerprints also start to form on the fingers and toes.
Your baby may be swallowing up to a liter of amniotic fluid per day.
The skeleton is transforming from cartilage to bone and the bones begin to harden.
As your baby will start to be able to hear around now, this would be a good time for you and the other family members to start talking to your baby or providing other forms of auditory stimulation.
During your pregnancy, your blood pressure is lower than before, and hence you may sometimes feel dizzy or lightheaded. Take your time especially when getting up from a horizontal position.
Sleeping may be increasingly difficult now, as your body grows.
