My house is fairly small, and my twin 2-year-old boys are pretty much across the hall from us. I am a light sleeper. Most mornings I hear some sort of sleep sound from one of them at 4:30 or 4:45. They are not waking up (well, sometimes they are), but they have gone through phases of waking up pre-5am for weeks on end. That dread alone seems to keep me awake. So I'll hear a little cry or groan from one of them and I just can't get back to sleep. What do other light sleepers with kiddos do? I can't bring myself to wear earplugs because I feel like I need to be able to hear them if something is actually wrong.
