M.M.
It is hard not to give in, consistency is the key to making this work. My 2 1/2 year old has been coming to bed with us since we recently switched her from her crib (where she never woke up or cried in the night) to her toddler bed because we moved and weren't bringing the crib with. We've also been weaning her from the pacifier so at night we tell her she may not have the pacifier if she leaves her bed. That has worked the last two nights. She calls to me in the morning and is so proud of having stayed in her bed. I praise her and haven't found the right treat, so have been giving her a fruit roll-up (until I can get to the store and find other rewards). This morning she even woke up dry and went potty, so it was a double celebration. Good luck!
