Nap schedule

I've heard that most babies on 3-4 naps a day will have 2 long naps and then the last nap of the day would be a catnap. Mine is the total opposite. His first nap of the day is always 30 minutes long no matter what, even if he is tired and even when I leave him a half hour longer in the crib (he'll play, get drowsy, fall asleep for 2 seconds and wake up again). Just wondering if anyone else has a baby that does this. Is it okay? I assume that some day when he transitions to 2 naps it would be easier to drop his last nap if it was a catnap but his last 2 naps are the longest so I'm not sure how that would work out 🤷‍♀️
