Naps and eat play sleep?

Okay so my LO has finally started taking naps longer than 30 minutes (most days) but still takes around 5 naps a day.. one or two naps are long (1.5-2 hours) and others are quick 30 min cat naps. My question is for those who went from 5 naps a day to fewer (3 or less), how did that transition happen? And how do you maintain the eat play sleep routine if they are napping less and awake longer? I want to make sure he gets lots of food during the day so he doesn't need 2 feedings a night. This parenting business is hard, haha
