Tameka's newborn baby is awake for several hours during the night and often sleeps during the day. at what age will her child establish a pattern of sleeping mostly at night?

Between three and six months old.

Explanation:

Between three and six months old, many babies begin to sleep all night. During these months the baby is unlikely to sleep 10 hours at a time, but will likely start a long, uninterrupted sleep, waking up to nurse only once at night. At three months, you should sleep 9 to 10 hours a night. From six months on, you can sleep up to 14 hours a night.

When she starts sleeping all night, the baby needs two or three naps during the day. These moments are very important to both him and his parents. The child needs to rest to be less irritated and enjoy the day. Parents also need some rest and can enjoy their free time to do everyday tasks.
