I'm not going to lie to you. The first night was ROUGH!! I don't know any mom that likes to hear their baby cry. But I knew in the long run I was doing what was best for the both of us. So I cried right along with him next to his crib. It lasted about an hour and he finally put himself back to sleep. He didn't get up again for the rest of the night. The next day his little eyes were so red and puffy from him crying. But I knew that this needed to be done. The next night he slept all the way through and has only woken up once that I had to go back in his room to let him know I was still there. The rest of the time he has put himself back to sleep. Good luck to all of you that also try this method. For us it has worked great!!
