Sleep : Sleep requirements are a very personal thing. Most people need 7 to 8 hours of sleep in order to feel awake and fully functional the following day. There are those few select individuals who can get by with fewer hours of sleep and be unaffected by it and there are others that require more. The key is getting to a level of rem sleep, so called because it is noted that the eyes move rapidly. This is the most restful stage of sleep where the body recharges itself. Individuals cycle into and out of rem sleep several times a night. This is why it is important to have a sufficient amount of time asleep in order for the body to recover from a days activities. The most important aspect of sleep is to maintain a regular sleep and wake pattern seven days a week. Follow the link for information regarding good sleep habits. ...Read more

How many hours sleep usually for two month old baby.

12 to 14 or so...: It really depends on if they are alert and awake when not sleeping. Some babies will be ok with 10 to 12 hours total, while others need more.

If the baby is alert, and interactive, you're doing fine. ...Read more
