M.T.
I went through this with my son when he was 14 months old. He didn't need food, just attention. I couldn't bear to let him cry it out. (my parents suggestion) Instead, I would go in and talk to him in a stern voice. I wouldn't pick him up, or touch him when he held out his arms. I would just tell him it's night time and he needs to sleep. It took 3 nights. After he learned I wasn't getting him out of his crib, he stopped crying. He would still wake up in the middle of the night, fuss, babble, and then put himself back down again.
GOOD LUCK!
