K.H.
I am going through the same exact thing right now. My son is 23 months and won't sleep in his toddler bed. He was perfect in his crib. I have been really concerned about this because I can't open the bedroom door because he is sleeping right in front of it. We have not completely solved the problem, but he's much better now. We do the same routine every night. He takes his bath, gets a snack, brushes his teeth, and picks out 2 books to read. The whole time I keep talking about what we are going to do next because it is almost bedtime. He says good night to everyone (he has two older sisters that I make "pretend" that they are going to bed too. He tucks them in). Then we read his books. I don't make him lay down in his bed yet, but he cannot get out of his bed. The last story I always read is 'Good Night Moon'. Then I tell him that Mommy has to go to Mommy's Bed and Cayden has to stay in Cayden's bed. We leave the door open now and watch him in the video monitor. The first couple of nights, he cried and tried to get out of bed, but everytime we saw him start to get out, we would say, " Stay in Bed". After 4 nights of this, he now plays in his bed, calling for me, but not crying. He got up in the middle of the night because he fell out of bed, and as soon as I got into his room, he climbed back up in his bed and went back to sleep. Oh, I forgot.... at naptime I would bribe him. I would tell him that if he stayed in his bed and took a good nap, he could have a popscicle when he woke up. This worked really well and as soon as he woke up, I would give him his popscicle.
I hope this helps you. Consistency is the key!! Don't give up!!
