Naps at 12.5 month old

My LO will be 13 months and Before he turned 1 his naps were 9-11am and 1:30-2:30 or sometimes 3-5.

Since he has turns 1 has naps has changed a bit. It’s either him napping from 10-2 and no nap til 7:30 or 10-2 and napping around 5 for 1 hour or so.

I’m curious if his transitioning to 1 nap instead of 2. I just think his naps in the morning are a bit long. He gets up between 7-7:30 and bed time is around 8. Thoughts?
