Bedtime temper tantrums

Er

My son just turned 1 about a month ago. The past few days he has been having huge temper tantrums at bed time and nap time. He has everything he needs. He stops the second we come back into his room, and starts as soon as we put him down or if we wont pick him and just hug him or pat his back. He uses his fake cry so I know he doesn’t need me, but I can’t stand to hear him cry. This goes on for 2-3 hours every night. And at least an hour at nap. He would typically fuss for maybe 10 min before falling asleep before this last week. I’m hoping this is just a growth spurt/sleep regression/or teething. I really don’t know what to do with him but he is driving me insane.
