Hi L.,
I can feel you!!! I went throught the same thing with my son who is now 5. The best thing that the doctor told me to do was start putting her in her own bed alone, with his favorite teddy. It was very hard, we had to keep getting up in the middle of the night when he would come into our bed, but after a couple of weeks he finally quieted down, and stayed in his own bed.
What I did, was about a half an hour before bed, I would put him in his bed, read him a story, and snuggle for about 10 mins. When I left the room, he would cry and scream, and come out running after me, but this passed after a couple of weeks. It was very hard on us, but we made it through it. You also may want to start doing the same thing with your other 2 girls as well, this way, your hubby can "move back into bed" with you. You can also start a reward system for the girls, for each night they sleep in their own bed, make a chart and put a sticker under each of their names, and at the end of a full week, give them something, whether it be an extra 1/2 hour of T.V. on a Sat. night, or a small toy, extra time outside, Something that they enjoy. If you do it all at the same time with all the girls, you can tell them all "WOW! Look at all my big girls". It is also ok if you wake up in the morning and the girls are sleeping together,(according to my boys pedi. They are looking for comfort, but you have to be firm about them not sleeping in your bed. As for the ear thing with other people, if you are holding her, and she starts playing with your ear, just move her hand and dont say "thats bad, or NO!", IF she asks you why you are moving her hand away, then explain to her that it is not confortable for you, and you would like it very much if she wouldnt do that. In time she will stop. I promise!!!! Good luck! If you need you want to chat, just drop me an email!
Take Care!
