Fights Bedtime

Any other April babies fighting bedtime? Our son used to go down SO easy, no tears. Would either fall asleep while I rocked or just soothe himself in his crib. The past week he’s not having it. Cries, doesn’t want me to put him down, or even fall asleep for that matter. He takes 2 naps a day around 10:30-12 and 2:45-4:05. We’ve never done sleep training, he’s rocked to sleep for naps in less than 5 minutes. He sleeps through the night, but not sure if I could be doing something different to make bedtime better for him.
