I don't have any advice on how to keep your DD to sleep in her room but just to let know I am having a similar problem with our 2 year old DD she screams everytime she has to go to her room to sleep and DH has decided not to get her a big girl bed yet!!
She already knows how to climb out and up and down and under and She knows how to climb in!! I think personally it is high time that She is moved out of her crib!! When she is in our room a sleep on our bed she sleeps so great!! Dh however seems to have diffrent view on this issue!! Maybe he will break down and get DD a matress , boxsprings, and bed railing!! We already have the headboard and footboard!! DH's Dad said we could even have the Matress, the Boxsprings, and the bed railing that is a twin for DD and that would fit perfectly on this bed we will be using !! Now I need some how to convince DH!! Praying for you and that your DD will want to sleep in her room more !!
