Like others said, cry it out. They'll sort it out before long. I do go in, but just to lay them back down and make sure the soother isn't overboard. That's it! Some of my parents come to me now for advice on how to put kids down. I sat during my break one day texting back and forth with one mother who was trying my method. She was so upset by her crying daughter, but eventually, she went to sleep and stayed asleep for 2 hours. Sweet victory
