Transitioning from two naps to one

Hey everyone! My LO is 14 months old and he seems to be approaching the transition from two naps to one. Any advice on how to do this? Cap the first nap, or the second, or both? Stretch the morning wake window? I’ve heard lots of different tactics, but I’d love to hear what worked best for you!

Also wondering how to approach his meal-times as we make this transition? Should I be switching lunchtime to before the first nap (instead of after)? Any tips/tricks are greatly appreciated!
