Are anyone else's babies naps changing?

Robin

My baby is almost 5 months and he was taking about 4-5 naps a day but lately he has been sleeping longer at night and then taking one long nap in the morning and then one long nap in the afternoon. He used to Catnap 25-30 minutes each nap and stay up an hour to two between each and now he's napping 2.5-3 hours in the morning and afternoon and staying awake 3 hours in between. I didn't change anything, he just started doing it!

Anyone else?
