We never bought a baby monitor because we co-slept. Now she's in her crib, but it's just outside of our bedroom. She's turning 1 soon and we plan to finally move her into her own room (downstairs). But I'm not sure if we'll really need a monitor since she's a little older and fully mobile.

How long did you use or plan to use your baby monitor? For those of you with LOs that are older than 1, do you think it's still useful? When will you take it down?
