Video monitor- when did you stop using it?

We’ve been using a video monitor since baby was 3.5 months old when we moved him to his own room. I never could’ve moved him out of our room without it. He’s going to be 14 months old soon and I still feel like I can’t function without it! The safety and security of being able to check on him whenever I want without waking him up is something I’ve gotten so used to, and I can’t even imagine not using it. I feel like I’m so attached to it that I’ll never want to stop! When did you all stop using yours, and was it hard?
