Monitoring the Situation

Moms, Dads —– need consumer advice stat—

We are an Army family. I am married to a junior officer and we live in government-assigned quarters. This means the homes are “intimate”, so I have not needed a baby monitor in order to hear a waking napper. However, we will spend the next month at my folks’ house staying in a back carriage house. Thus I need a baby monitor that works well. The range doesn’t have to be amazing and I think I will even be ok with one that is plugged into the wall – just need one in the front house so I can hear the waking angel out back. Any and all suggestions welcome but please hurry, we leave in six days.
Thanks in advance, team.
