I'm assuming that since she is walking she knows how to go down from the standing position. Can she do that in her crib? If not, just hold her legs and arms and go through the motions with her until she catches on. Thanks for giving me the name. I have always used the Ferber method for sleep problems, so I recommend that you stick with it for a little longer. Knowing that this too will pass, decide that there might be a night or two of lots of crying and use the method with some alterations. After 15 min go with 20, then 25, etc. Don't pick her up. Before you put her down for the night, give her a big hug and say in a serious tone, just as if she understands every word, "Tonight you have to go back to sleep if you wake up, no pick up" Then do it. Let her see you during one of the check ins so that she cries so hard that she gets exhausted and falls asleep. She will not want to repeat that, and the next night will cry less. You will have your good sleeper back again. She is a pretty late walker, talk to your Dr. about any possible connection between that and the sleep problem. IS she possibly sleep walking, I don't think so at such a young age. You are correct to worry about her forming a habit of the couch sleeping, and remember the twos and threes are coming up, you don't want to enter them with her already manipulating you.
