Hey there & welcome to the boards
!!!
I moved my lo from our room at around 5.5-6 months because I found that she was waking alot and I was attending to her every move and also she was waking/stirring from every caugh, snore or noise we were making, lol...
I also wanted to comment on the naps. He is doing exceptionally well with the daytime naps & I think he might actually be having too much daytime sleep (which in turn can result in nightwakings as well).
He should be able to do 2.75-3hrs during the day, so I would perhaps try something like this:
9am - morning nap (1.5-2hrs)
11am - wake
2pm - afternoon nap (1.5-2hrs)
3.30/4pm - wake
6.30/7pm - bedtime
He might be ready to drop the catnap OR I would wake him from the morning & afternoon nap at 1.5hrs & do a catnap. If you are going to push his pm nap to 2pm, I would do it in increments so that he doesn't get overtired. I think the catnap is too close to bedtime. He is probably waking so early in the morning as well becuase he is having too much daytime sleep.
Pesonally I am all for moving them into their own room after 6 months (or before if it helps) so I would say go for it! But I think the NW are to do with daytime sleep as well.
Just a thought
