what to do when baby already fell asleep on their own?!

Liam would sleep 9pm-7am with MAYBE one feed usually around 4-5am.

not? well, he's woken earlier every night the last week. first3, 2, 1 and last night just 2 hrs after bedtime. he's not Hungry, won't eat. just fussy til I hold him back to sleep with a paci and blanky and LOUD white noise. then repeat every 2-4 hr.

I just read it's permanent??!! WHAT?!?!?! and says you have

to teach them to sleep in a new way. wth!? he already falls asleep on his own and isn't fed to sleep!
