Refusing naps and taking 2 HOURS to go to sleep

Ma

All of a sudden my child has turned demonic. He used to take naps (albeit they were short) and used to go to sleep easy at night and sleep almost all night. Now the last week it’s taken me 2 hours each night of him screaming while I try desperately to get him to go to sleep. Naps aren’t happening. Period. He’s been up since 7 and it’s 1pm and no nap yet. I’ve been trying to get him to sleep since 8:30am. I even took him for a drive which I said I would never do to get him to sleep.

I’m about to lose my damn mind.

Anyone else? Wondering if this is that 4 month sleep regression hitting us early... (He’s 15weeks)
