Help! 8 month old son still eating at night 😫

An

My baby still gets up at night to eat every three hours.I’m going into my second trimester and I’m beyond exhausted. I also have a 12 & 2 year old son as well. I have my hands pretty full as a SAHM! I’d really like to get a good nights rest because I never sleep my third trimester. I’m super excited this is my first baby girl after three boys 💕 I need help my mother, the doctor, and everyone is at my throat about night feedings. I’ve tried the pacifier, co-sleeping, and nothing works.
