Waking up earlier

So little man was cutting some serious teeth about a month ago and he would wake up in the middle of the night. Now that’s all over but he’s now waking up over an hour and half earlier in the morning 😫. Every morning. He used to sleep until about 7 and just talk to himself in his crib for ten-twenty min. For the last week he wakes up In a blood curdling panic by 6. The last three days it’s been 530. Any ideas on what’s changed or how to adjust this?
