We have a monitor, but only because we got it in a package with our breathing monitor. But we have used it once and that was on my 30th because there was a fair bit of noise going on, and DH wanted to hear if DS was upset or not.

That being said though, we have a teeny tiny house, and thin walls, so there isn't a chance in hell we wouldn't be able to hear the kids.. lol

Don't let anyone scoff at you honey - its your baby - do it your way.
