Waking too soon?

So my son usually gets about 2 and 1/2 to 3 hour naps once a day, and he sleeps pretty good throughout the night but the issue that I have some may come across is the last couple of days he's been waking up early into his nap. Today for instance he woke up an hour and a half earlier than usual. What do you guys do in that situation? Do you just leave them and wait to see if they settle back down or go get them?

I waited a few mins , he had woken up and started to cry a little, I continued to wait a few more mins and he had laid back down but was just laying there playing with his hair until he stood back up...so I gave up and went in. 🤷‍♀️
