23 month older fighting sleep?

Mel

My daughter is almost 2, she is driving me insane with her sleep. She will wake up some days at 10:30 - 11 AM and not sleep all day which okay whatever but then by 8-9 I would hope she would be tired for bed and sometimes she is so tired and will fall asleep but then she will wake up around 3-4 AM and want to go downstairs to play.

I can’t understand please is this just some sort of phase ?!?

When she wakes up at 11 AM there’s no sense in putting her to nap at 4 PM when she starts to show she’s tired but fights her sleep
