Follow cues or awake time

Hi ladies, just need advice. My boy schedule was:

6.20 wake up

1 nap about 9-10

2 nap 1.30-3

bedtime 7

But last 2 weeks he is waking up extra early as 4.30am😴😵😵not going back to sleep. not sure if its sleep regression or teething or something but if he wakes up 4.30 , should I put him in bed normal at 9am like I used to (which is long awake window) or should I just adjust his schedule and put him in bed when he shows signs of tiredness( which is about 6am)Last week days I tried put him at 6, he woke up 6.30 and then next nap was at 9.30 so basically he was back on his normal schedule but then he has 3 naps a day which dont know if is it ok..???
