Why is he not settling

Cassie • 🎉🎃🍁🍂 blessed with a beautiful 3 year old boy a 2 year girl and a 9 week girl👨‍👩‍👧‍👦
He's normally a really good sleeper and sleeps all night, but tnite is the complete opposite, I've tried laying with him, telling him firmly (no playtime its sleep) soothing him, teething gel, he had a bottle of milk, he's been changed, and he's giving the type of scream like he is crazy, he's dead tired and just Won't give in, instead he wants to sound like the exorcist while trying to sleep, he's babbling and rolling back over and blowing bubbles X just not having it's what else can I do to get him to sleep, he's now been awake since 1 o'clock and it is now 3:57 😭 mamma tired big time xx
