Hi J.,
My son was the same way when he was that age. It's hard, I know. But all I did was when he was sleepy, I put him in his own bed & if he cried, I'd let him cry it out. I know that sounds mean, but it really works. He only cried off and on for no longer than 15 minutes. Don't break. It's hard to hear them cry especially when they cry for mama. If you go in, he's catch on quickly that all he has to do is cry & you'll come running. I hope this helps. Let me know how it goes.
