Hi, we are trying to make some changes to our 9 week olds sleeping. At the moment she goes down at about 11ish for about six hours. We wanted to add to the start of that so she goes down a bit earlier and were planning to try putting her down at about 800 for a couple of hours, feeding her and then putting her down again at 10 or 11. What i wondered is whether it is ok to leave her on her own in the room for that first bit of sleep while we go downstairs and eat etc? This might sound silly but she's our first and has always been with either of us so far!
