Just that really. My DD is great at self settling, I put her down awake and leave her to it, but I can see on the monitor that she's rolling around, sitting up, pulling up to kneeling, lying back down again, etc, for ages. She occasionally bables but if I didn't have the monitor I wouldn't really know she's awake most of the time. Yesterday she took an hour and a half to go to sleep. She was never very quick, but was more around 20-30 minutes usually, nowadays seems over an hour most days. Just wondering if this is normal or am I putting her down too early? She does seem tired on an evening. Normally she's in bed around 7 with the aim of asleep by 7:30 but lately it's 8-8:30 when she's falling asleep. She's 15 months.
