9 months old sleep regression HELP PLEASE

ca

My son won’t sleep at night😔

I’m tired and husband is tired

I think is the 9 months old sleep regression and i dont know what to do

He would go to bed at 10 pm and wake up at 10:30 and wants to play until 2 am

I asked my husband if we can purchase the taking cara babies program but he said its too expensive😣

Then during the day he only sleep while nursing

He is always looking for my boob to self soothe

Any tips to overcome this?
