Anyone else dealing with a major sleep regression.

He takes a beautiful morning nap but he fights the afternoon nap.

He falls asleep at bedtime easily and usually wakes up 2x a night to eat but at our second night feeding about 2:30 a.m. or so I can’t get him to fall back asleep easily. He drank 6oz, I changed his diaper just incase he was uncomfortable and rocked him….

He’s been up for the past 1.5 hours whining struggling to fall back asleep (not like him at all). When I picked him up he almost immediately fell asleep in my arms…

Is this a regression. He’s not sick. He may possibly be teething but it’s never caused him to regress with the past 3 teeth.
