Kids at 2 years old, commonly get sleep tweaks.
It is a phase. It passes.
Both my kids were like that too, at that age.
It passes.
Just keep to your usual routines for bedtime etc.
And watch for his 'cues' of being tired etc.
Some kids, like my son, actually get more "hyper" the more tired they are... it is a kids' way of FORCING themselves, awake.
Have a 'quiet time' as well, in the afternoons.
Make everything QUIET and dark etc. Calm. Even turn off the lights.
No horseplay at night... otherwise it just keys up a kid, again, and ramps them up. And then they cannot calm down.
Try massaging his temples or feet.
That puts my daughter to sleep.
He is having trouble, keying down.
ALWAYS have a WIND-DOWN time, ahead of time, BEFORE naps or bedtime. Even 1 hour, prior.
Once my kids hit the toddler ages, it took time to wind-them down. I started the wind-down process.... 1 HOUR, prior to their naps or actual bedtime.
Make it a regular, routine. Every night.
Try also, NOT having a constant stream of activities. Kids do not need that. Have... just quiet time too. Just have, quiet. Kids, ALSO need, to just have 'NOTHING' to do sometimes. So that they can just relax or self-regulate their minds/physicality.
Kids do not have to be constantly entertained.
Kids, this age and on, have a harder time, keying down. You have to cue them.... prompt them... make the atmosphere... CALM and dark and quieter. They have to be assisted, in this. They are not self-reliant about it, yet.
