What moms do
- 1
Stick a battery door or window alarm on the front door, the back door or the slider to the yard.
- 2
Once a toddler moves to a big-kid bed, some put one on the bedroom door so they know when it opens at night.
- 3
Travel ones go on the Airbnb or grandparents' doors, especially when there's a pool.
Why moms swear by it
Toddlers learn to open doors quietly long before they learn when not to. A chime tells you the second it happens, wherever you are in the house. It's a heads-up, not a lock, so it works alongside the latches and gates you already have.
