Baby is off

Kaiti

For the past two weeks my babe has been giving us a tough time at night. He’s sleeping through the night, but is hard to go down. I go off of his cues and he’s showing all signs of being tired but the second I put him in his crib he wants to stand and party. It’ll be a good 15 minutes of play/cry until he sleeps. This was never an issue before and I’m wondering if anyone else is experiencing this?
