I think I am going to start transitioning Colin to his toddler bed. He isn't climbing out yet, but he really seems to enjoy the elements of a "big boy bed": the pillows and soft blankets. He hasn't been sleeping great but if I put him in my bed and snuggles right up to the pillow and is out. I can't figure out if it is b/c he is near me or if it is the bed. Last night (since Andrew was gone) I put him in our bed in the middle of the night on Andrew's side. I didn't touch him...and he slept soundly, even allowing me to get ready without waking. Oh, and sleeping in my bed is not something we do regularly...so if it is the bed he likes, he is getting his own.
The toddler bed isn't my favorite, and I would much rather get him a nice new comfy mattress and bed, but I am not prepared to take on that expense and then it backfire! If we are getting a REAL bed...he is also getting a room make over to make it more like a little boy's room. So you can see how I am holding off on that expense until I know he does well.
I am curious as to what made you switch to a toddler/twin bed and if you had any tips if we hit a rough patch.
