R.D.
My son is 17 months old, and while he's a holy terror while he's awake, falling asleep is no big deal! BUT... we've been doing the same thing for forever with him. Persistance is key mama; you've got to undo what's been done. My son is on a very predictable schedule... he wakes up around 7:30am, naps at 9:30 and 2:30, then goes to bed at 8pm. When we put him down for naps or for bed at night, I use my calm and quiet voice, hold him close (with his blankie) and keep repeating 'night night, love you' and he repeats after me. I kiss him, put him in his crib (while keeping the lights off), cover him with his blanket, and walk out, closing the door behind me. He might yell and cry for a minute, but then he babbles to himself until he dozes off. I truly believe that using my calm and quiet voice for nothing BUT bed/naptime helps a LOT!! Good luck :)
