The bedtime routine works a treat here. We started it when Jacob was around 8w old and he came to learn very quickly, that having the bath was associated with a nice big sleep. Everything was very relaxing....a bath with Mum or Dad, nice big feed, dark, quiet, warm room etc etc.

We did things to try and help him distinguish between night and day, e.g. put his bassinette in the loungeroom for sleeps during the day so he was around light/noise. That meant he was only in the dark of a night time. We don't do this any more mind you, as now he's older he much prefers to have the room dark for day time sleeps. But in the early days, that really helped him work out the difference.

I wonder if a hammock might be something she would sleep in? Perhaps she would feel more safe and secure in that as opposed to her cot?
