With my daughter, who's now 6, we had to commit to a week of bad sleep. We just took turns going in and putting her back. And I found that a good kick under the covers got my husband up for "his turn" :) It did take the full week of night wakings to get her to realize that sleeping in our bed was no longer an option. With my twins, who are almost 2, my son gets up on a regular basis. He's still in a crib, so he screams and cries for one of us to come get him. For awhile, we were taking him out, rocking him, and then putting him back in his crib. Now we see that he expects this, so a couple weeks ago, we just started going in, making sure everything was fine and not even picking him up. We just told him it was bedtime and goodnight. Yes, he often woke up his twin sister, and sometimes she cried, but again it took about a week for him to realize that he didn't have the option of getting up for some middle of the night comfort. As for the little green light, black electrical tape works very well to cover it up, too. Good luck!
