If you just want to hear your child, a basic baby monitor is a good choice. A basic baby monitor sends the sounds of your child to the parent unit via a DECT, digital, or PMR connection. Before you choose a baby monitor, it's important to know what extra functions you would like to have. For example, you can choose a baby monitor with lullabies, a two-way audio, or a night light if you want to soothe your little one from a distance. Do you have multiple children? Check if the baby monitor is expandable. That way, you can keep an eye on multiple rooms via one parent unit.
