When the baby is asleep, you might want to leave it alone to get some rest yourself or do some other activity. A baby monitor will help you to supervise your child and you will be notified as soon as the child stirs or cries.
The baby monitor is the ears of the parents, and nowadays even the eyes. Designed as a little one-way walkie-talkie, with or without built-in camera, the parents can listen to every sound the baby makes while they are not around. This gives them an opportunity to do other activities and also prepares the baby for the fact that it can be asleep without the parents present. Think of the baby monitor like an electronic babysitter.
In my opinion, I think it is necessary to have baby monitor for family which have a baby.
