For those with sleep trained LO's where you did some form of CIO... post-sleep training how do you deal with MOTN wakeups if they happen on occasion? LO sleeps through the night and if he cries a bit going down, I leave him and check occasionally if it gets bad. But for those rare wakings in the middle of the night (say, a noise disturbs him or thunderstorm or whatever)... if they cry, do you go to them right away? Or leave for a bit and wait? Please share what you've done and what your protocol is!
