Waking up early...again...

Hi ladies, I am not sure what to do.My boy started waking up early, like super early.

His schedule before was up at 5:45-6:30. then he had nap around 12 until 3 and then bedtime 7.30.

Last week he suddently woke up one day at 4am..and its been like that since. Its been a week now .Wakes up usually between 4-4.30😴😴🥴😵🥴His tooth was cutting through but its done now and he still not sleeping longer😔

He wakes up all fresh and full of energy. Then he lasts still until 11.30 for his long nap until like 2-3. and goes bed still same time 7.00-7.30.

He sleeps through the night without waking up.I thought its gonna go back to normal but I am losing hope. Any ideas what to do? should I still wait if it will go back to normal or just try something to do about it?

Thank you for any help😘
