Ugh. Kellen was doing this about a week ago. He knew how to get me in there...would throw his paci on the floor and listen for my footsteps. The only thing that seemed to work was making sure that I didn't get him out of the crib. I would go in, rub his back, lay him back down and walk out. He had to cry it out a bit but I knew he didn't really need anything because he'd cry and "listen" to see if I was coming in...when he didn't hear me, he seemed to get the hint that it was night time and to go back to bed. Lots of prompting though. I think it's just a phase. Hopefully!!
