Cut down to 2 naps?

my 6 month old is a great sleeper at night (9.5-10 hrs with only 2 night feedings). We are currently doing 3 naps/day every 2-2.5 hrs but they have seemed to be getting shorter (like 25-30 mins)

We have had solids for about a month now, so I don’t know if that could be the culprit. Do you think we should cut down to two naps every 3 hrs?!
