Wow, I think I turned our monitor off very early compared to everyone else! I'm not exactly sure when it was, but definitely before 12 months. I was finding that DS was waking a lot at night, but would often settle himself very quickly and not need me. With the monitor right next to my head, I was waking every time he made a noise. Since turning it off, I still wake up as soon as he cries, but I don't hear every single noise. I figure if he needs me he will be loud enough that I will hear him! I am a fairly light sleeper though. If I'm ever not home (very rare!) DH has the monitor on.

We do still have it connected and often turn it on in the evenings so that we can hear him over the noise of the TV!
