My LO is 4 weeks old and only wakes once during the night for a feed - however, if she is awake when I put her down or if she wakes up (but not for a feed), she shuffles and snuffles so much, I am wide awake - long after she has gone back to sleep on her own!
I am pretty sure in her own room, I would only respond to the -feed me- cries and sleep better than I do atm - but she is so little, and am aware of the -six month rule-.
What age was your LO when you put them in their own room?
Also, is it worth putting her in her room but still in moses basket rather than in her cot?
TIA
