So I need to know all the tips and tricks here. I'm dreading making this switch, but im due in January with baby #2 and we'd rather just get it done and over with now so we have only 1 non-sleeping child to deal with at that time instead of 2 (hopefully).
We got a queen size bed with a bedrail & blackout curtains for both windows in his new room (we are putting DS1 in the bigger room and when ds2 is ready, he'll go in DS1's old room where the crib is). We plan to put a baby gate on the doorway to prevent escapes. He'll have his white noise machine on like he normally does for nighttime sleeping and naps. If I need to, I'll lay next to.him.and rub his back until he falls asleep, but I'm afraid he won't even lay/settle down long enough to fall asleep!
I guess i feel extra guilty bc he loves his crib and sleeps so wonderfully in it. He's only 22mo and it doesn't seem like he quite grasps whats going on regarding the switch to a bed. We bring him in his new room all the time and explain to him that its his new big boy room and we lay on his new big boy bed and explain that its his and all that jazz, but he's got an expressive speech delay, so he isn't quite able to talk to us and clearly communicate his wants/needs with words yet.
Anytime we lay on his new bed, he gets all riled up and starts bouncing around like a mad man bc he thinks its time to play. How do I get the point across that his bed is for resting/sleeping and get him to stay in it (besides repetition)? Im afraid I'm going to turn my rock star sleeper into a sleep hater!

Re: Talk me through this (re: transition to big boy bed)
I guess technically I don't have to do it NOW because I doubt she'll be sleeping in there for awhile yet, but .... I feel like maybe it's smarter to get him transitioned now anyway before she's here?
The box springs and mattress are on the floor so he can easily climb up and down.
I ordered his new comforter and sheets online, then had him help me unpack the box, put all the bedding in the washer and dryer, make the bed, etc.
We also read the Elmo book "Big Enough for a Bed" for several weeks prior.
We follow the same evening routine as always -- bath, lotion, pjs, bedtime music on, snuggles, sit by the bed for a couple minutes, then leave the room.
We have had a couple nights where bedtime took longer than usual -- extra snuggles, sitting by the bed longer, walking him back and tucking him back in if he comes out of his room, etc. By and large, however, it has been a smooth transition.
He does have a lovey/security object and I think his attachment to that has helped him transition.
Sorry so long. Wanted to provide plenty of detail in case anything might be helpful for you.

@desertsun keeping him on the same room isn't an option bc all of our bedrooms tiny as hell, and the room he is in right now isthe smallest of all, so its best to move him to the bigger bedroom with the queen bed.
Eta RE: anchoring stuff to the floors...MH and my brother are in there anchoring the dresser to the wall as we speak
HTH!
Unfortunately all of our rooms are really small, so moving his crib into that room Temporarily wouldn't be an option either (the queen bed is already set up in his new room). I guess maybe we'll try with reading a book, snuggling, amd then a nap in the bed first and go from there...hopefully it'll be a smooth transition since we're keeping his bedtime routine the same...just a differnt bed/room.
