Babies spend most of the day in sleep, but some babies always sleep more during the day and are sleepy and full of energy at night. This is mainly because there is no difference between day and night in the mother’s womb, but when the baby is born, he or she will have to face the difference between day and night. It will take some time to help your baby establish the concept of day and night, and it is best to start at an early age to develop good sleep habits.
