This is my first post - I need some advice, and I'm sure some of you can help. I've searched the archives and can't find much on this particular situation (forgive me if I just haven't looked in the right places...). Lots of people are familiar with the issues of putting a baby and a toddler in to share the same room, but I can't see much about the issues around slightly older siblings. DD1 complains bitterly in the mornings that she is tired because the little one a) wouldn't go to sleep b) woke up in the night and made a noise c) woke up early and switched the light on, or all three. This morning DD1 was in tears and beside herself. She's usually a happy little girl, who likes school, and isn't generally grumpy about getting up. On nights when they've both slept well DD1 is fine in the morning. We could put them in separate rooms, but they still want to share (even DD1 doesn't want to go in a room without her sister, despite the moaning about being tired). How did any of you deal with this, or similar?
