A mother shouldn't leave her baby for an extended amount of time until about the age of 36 months, when he has developed some concept of time.  After constantly hearing a heartbeat and being 'held', being put down for long periods of time can be quite scary and lonely. Some infants will go down easily and seem content to be alone. However, in some situations they might have learned that no one will come if they fuss.

Between 4-7 months of age, babies develop a sense of "object permanence." They're realizing that things and people exist even when they're out of sight. Babies learn that when they can't see mom or dad, that means they've gone away. Your baby won't realize that they're their own separate person until they're about 6 or 7 months old.

It typically ends by the time a child is 3 years old. But your baby will not feel abandoned by you when you return to work. Mostly because he or she is a baby who really has no idea what “work” is, but also because you're a good mom who loves her baby no matter what.

Fortunately, research suggests that children don't experience any harm when their moms work outside the home. The decision to stay at home or return to work is very personal, and there is no one “right” decision for everyone. Keep in mind that a happy mommy will mean a happier baby!
