8 month old waking up too early

So my son is pretty much always slept really good he’s goes to sleep between 8-9 and would sleep till 8-9 maybe even 10 some days. But for the past week he has been waking up almost every two hours and has been waking up for the day 6 and I’m not having it at all I’d love to get more than 5-6 hours of sleep a night of solid sleep!! Idk what to do at this point it’s driving insane
