No matter how attentive of a parent you are, you can't be with your baby all the time. But a cheap baby monitor will help you to feel like you are in the same room with your infant. It is important to know if your baby is crying or sleeping soundly, but you may not be able to hear it in a large house. A cheap baby monitor will give you the peace of mind that your child is just fine. You can even find cheap baby monitors with a small video camera, so you can keep your eyes on your little bundle of joy at all times.
