At 3 months, your baby may need 10.5 -16.5 hours of sleep a day. Some babies at this age can sleep for 6-8 hours at night and most will take 2-3 daytime naps. Keep in mind, however, that each baby is unique and that this is only a guide. Every baby's sleep pattern is different: some are erratic, while others are routine. All babies fall into an established sleep pattern eventually. Try to create schedules that work for both of you. Solid nutrition is an excellent way to contribute to sound sleep habits. By satisfying his dietary needs with adequate amounts of essential nutrients, you provide a better quality of sleep for your child, which in turn contributes to his healthy growth and development.
