1) Don't do those "evening activities" pre-bed. For some kids, (like my son), doing activities or physical things before bed, just WINDS him up. And gives him a 2nd wind. I told my Husband that.... many times. It does not calm my son down. THEN it takes another hour for him to wind DOWN.
2) Make the house, Dark and calm BEFORE bed. I'm talking 1 hour before bed. Turn things OFF. I only leave on 1 lamp. Nothing noisy. Nothing hyper. You have to set the stage.... PRE-bedtime. For sleep. AHEAD of time. A kid, needs to, change gears. They can't do that spontaneously.
What is happening, is your daughter is winding-down... WHILE she is already... in bed. And thus it is taking LONGER. WIND the kids down... BEFORE the actual bedtime.
3) Then, you verbally tell her, "wind-down time...." and "In 10 minutes... we walk to bed. Then cuddle/chat for 5 minutes to relax. Then bed time and Mommy leaves."
Give her loveys to sleep with, a flashlight for in bed, a cup of water nearby. That she can get herself. Tell her "Time to make your nest...." (ie: her bed all cuddly), then bedtime. My kids, love to call their bed their "nest." And they LOVE getting it ready and all comfy/cuddly before bed. Which, I also factor in this time, into their timeline of bedtime, so that bedtime is NOT late.
You have to verbally transition a child... as well as, doing it.
4) and yes, OVER-tired kids, can really make it mega hard, for them to go to sleep and to wind-down. Per my son, IF he is OVER-tired, he will actually get MORE hyper. My daughter just gets fussy but will pass out quickly. Each child being different. But I KNOW my son's cues. When he is hyper... it means he is TIRED. Dog, tired.
It will not be a trend. As a child gets older, they naturally change in mode.
How old is your daughter? Because, THAT, makes a difference.
ie: 2 year olds, TYPICALLY have lots of sleep tweaks.
ALSO, get her to bed, earlier.
Which means, starting the bedtime routine, EARLIER too. And that means, dinner needs to be earlier, too and the bath etc. 1 hour earlier, is what I do. And my kids are 6 and 9.
That way, they do not go to bed, late.
My kids, at their ages, go to bed at 8:00pm.
And they are, tired.
