My three year old was a terror at bedtime. My advice is routine, routine, routine. Get her used to the same activities in the same order every night so that her body trains itself to know its bedtime. With my kids it's a bath, teeth brushing, 15 min of reading to them, and they go to bed. I will allow them to take a book or favorite toy to bed with them most nights as well. ALso, a baby gate at the bedroom door works wonders. My sons' room is childproofed so that there isn't anything in there he can hurt himself on. All three of my kids are in bed every night at 8:30, and usually they are asleep before 9:00. It is tough to set up a routine at first, but, believe me, it is SO worth it. Good luck!!
