It is being physically separated from you, even for a moment, can make baby unhappy. He may feel anxious and begin to fuss and cry. He has a limited sense of time, so when you are out of sight, your baby has no idea when or even if you are coming back.

So you better choose the best time to leave your baby. It definitely is not good to leave him when he’s tired, hungry, or sick because he associates you with comfort and security.
