Help with 19month old sleep issues


So my toddler has been waking up at 5am every morning for the past month.

I used to nurse him once around 4am, and he would go back to sleep until 6:30 or so. I weaned him from nursing and he has been waking up at 5ish every morning and refusing to go back to sleep. He will just sit in his crib screaming. I do go in to check on him and tell him it’s still night time and go back to sleep but it does not work.

I put him down fully awake for bed and naps.

Help please I’m sooo tired and so is he!
