It's so hard isn't it. Watching them grow is the most amazing thing in the world but I just wish it didn't happen so fast!
A minute ago DS was this floppy, snugly little thing that wouldn't go to sleep unless I cuddled him. Just me, no one else would do and he'd bury his face in the crook of my arm.
Now I plonk him in his cot and he stands up and says "later potata" as I shut the door.
Don't feel like like you have to put him in his own room by a certain age. Just go with what feels right, whenever that is, and what is easiest. Ignore all the 'making a rod for your own back' nonsense. He's a tiny baby.
He's got the rest of his life to sleep in a different room, a few more months now won't make any difference at all.
On the other hand if in a couple of months you think you are both ready then do it.
DS went into his own room a month ago. The reason being that it was the right time for both of us.
He was reliably sleeping through the night without any misplaced dummy issues and he was starting to get disturbed by me coming to bed. It felt right and it was. He hasn't turned a hair at being in his own room. Not one difference.
Enjoy every snugly minute
