Daylight Savings Time screws up everybody's sleep cycle, which is why I think they should just QUIT IT! Sorry, that's a whole 'nother rant.
Do try putting her to bed earlier, rather than later. Too many people these days seem to forget how "over-tired" works; it makes kids antsy and seemingly over-energetic, makes it harder for them to relax and sleep. It does NOT mean they need less sleep. There may be a few children out there who are biologically different, but every child I've met whose parents claim that has been obviously sleep-deprived to me.
(Also, don't give her milk when she's going back to sleep - the sugars in milk are just as bad for her teeth as any other, and water will actually fill her tummy just as well, if temporarily.)
Your daughter is probably just at the age where she realizes there might be things going on while she's asleep that she doesn't want to miss, so she fights it. Keep night time as boring and routine as possible, but unfortunately, it's a tough time for parents. It might be a good idea to make Dad responsible for her now when she wakes up too early. He may have an easier time focusing on the need for sleep rather than wondering what else she might want ;). Good luck.
