M.M.
I'm just here to commiserate. My 2 year old was a rock star sleeper. 4 months ago she started climbing out of her crib, and the new bed is just not working well at all. Even with the same routine, same animals, same everything...she ends up in our room most nights. It is very frustrating, I agree. I just repeat in the back of my mind that 'everything is temporary.'
I wish you luck and patience!
