Benefits for you and baby
Better mental health
Stronger relationship with your partner
Reduced stress and anxiety
Left is best
The best position to sleep when pregnant is on your left side because it enhances blood flow to the baby, your uterus and kidneys. It can also reduce potential swelling in the hands, feet and ankles.
As baby grows, lying on your back puts pressure on major blood vessels and can decrease circulation to your heart and your baby. Stomach sleeping also becomes more uncomfortable.
