Nap schedule?

What’s everyone’s nap schedule and how long do their littles nap for? My LO sometimes naps twice, sometimes 3 times a day. Most of the time he’ll have either one or two half-hour naps and one 1-hour nap, but I’m finding the inconsistency is taking a toll on how he gets to bed at night. He’s usually exhausted and ready for bed at night around 6 no matter what time his last nap is but can sometimes have a hard time falling asleep if his last nap was too soon before his bed time (understandably). Just looking for some examples of what everyone is doing and maybe some tips to try to get his sleeping pattern more consistent ☺️ TIA!
