My two year old has been taking over an hour to fall asleep lately. Can anyone relate or have tips?

She is just up in her crib talking and singing to herself and her lovey.

Her schedule has been all over the place for the last few weeks. She used to be such a good consistent sleeper, but she started waking up at night singing/talking for hours. Then waking up early. Now taking even longer to fall asleep.

Today, she woke up around 7am, nap 1-230, in her crib at 730pm, still moving around now at 9.

Help!
