5am wake ups 😫

My girl has just turned 19months and for the last 2/3weeks she’s been waking at 5am screaming at the top of her lungs until one of us goes into her room and refuses to go back to sleep. She used to always sleep til 6.30. How can I get her to sleep in longer? I’ve tried changing nap time/bedtime etc but doesn’t seem to make a difference.

Does anyone leave books/toys in their LO’s crib/bed for them to play with in the morning?

I usually try and leave her when she wakes in the hopes she’ll lay back down again..but no..screams and jumps up and down.

Please help…from one tired mama 😫
