Typical baby sleep schedule for this age
By age 6 months, most babies sleep a total of 14 hours a day (between nighttime sleep and naps) and are capable of sleeping for long stretches at a time.
Between the ages of 6 and 9 months, many babies consolidate their daytime sleep into several naps, one in the morning, one in the afternoon, and one in the early evening.
Don't be concerned, though, if your baby continues to take more than three naps a day. Keeping consistent times for bedtime and naps will help regulate his sleep patterns.
When do babies start sleeping through the night?
Usually babies sleep through the night by 6 months – though some babies don't. If your baby now sleeps for eight or more hours at night, it means he's figured out how to settle back to sleep – a sign that you're raising a good sleeper. Congratulations!
If your baby isn't yet sleeping for eight hours straight, you're not alone. Many babies still wake up at night for feedings in the 6- to 9-month stage (though most are ready for night weaning, if that's what you choose to do).
Babies this age don't necessarily wake up because they're hungry. We all wake up several times every night for brief periods of time. And as adults, we put ourselves back to sleep each time – so quickly we don't even remember it in the morning. If your baby hasn't mastered this skill, he'll wake up and cry during the night even if he's not hungry.
Is my baby ready for sleep training?
If your baby hasn't yet settled into a sleep pattern that fits your family life, now might be a good time to try some type of sleep training. Sleep training methods can help your baby go to sleep more easily, sleep for longer periods at night, and keep more regular hours.
Why your baby may have problems staying asleep
Babies who were great sleepers may suddenly start waking up at night or have difficulty falling asleep between 6 and 12 months of age. Why? Sleep disturbances often go hand-in-hand with reaching major milestones in cognitive and motor development and with separation anxiety.
