Any ideas please?
DD is constantly tired, often grumpy and, I don't think, functioning as well as she should in school. At home she's always 'too tired' to read.
She goes to sleep well, usually, at about 7.30 or a bit later (never later than 8). Has always been an early riser but also shares a room with her 3 year old brother. Whoever wakes first invariably wakes the other one.
There is no possibility of not sharing a room. Neither of them will sleep with us (co sleeping was always a disaster, even as babies). If I get DS up so as not to disturb DD, she's really jealous and has to come downstairs too, so doesn't get any extra sleep.
Is there something glaringly obvious I've missed? They have a gro clock set for 6.30 on a school day but are often awake before this. They know not to get up but are still awake and talking. It's usually the little one who wakes the big one, but he's asleep sooner and can still nap in the day if he wants.
