J.O.
K. first off I am going to say this to you. You are doing everything right. The reason I am saying this is because I am sure that you are getting VERY frustrated. My 18mo old has had issues with naps for a LONG time. It gets hard I know. We have done a few things and I am going to pass them all on to you. I hope one will work for you. Yes you can let her cry it out or put toys in with her but try these.
1. Go all around the house and turn EVERYTHING off. Go thru each room turn off the room and tell it goodnight. This way she thinks that she will not be missing anything.
2. Give her a warm bath before nap time. Use the lavender soap the is relaxing. Dont forget to put on the lotion too. When you put on the lotion though give her a massage of sorts. That is also calming.
3. Give her a blanket that is only for her for bedtime. Ours is silky on one side. It never leaves the bed and the baby knows that it is a comfort thing.
4. Use music or a video to your advantage. We play a video and rock just before we put her down. The rocking and the video calm her right down.
This is not something that is going to work the first time. You have to stay strong and CALM. The little turkey will bust you out in a heart beat if you get frustrated and then you are sunk. A combo of numbers three and four are what did it for us. Good luck!! And dont forget to have you downtime dont use her naptime to get your house work done. That may be what she is hearing and wants to join you. Read a book that is what I do. The trashy novels are the best. The lack of reality crack me up!
