5 month old and sleep?

My baby is now 5 months old almost 6 months on the 23rd. He’s a horrible sleeper at night I mean horrible. When he was 3 months old he slept through the night and it was amazing. Then when leap 4 approached it’s been hell ever since. He wakes up frequently through the night crying. Even if I leave him there for a little bit to put himself back to sleep he refuses. He starts screaming until he’s red in the face. I’ll get up give him his binky back and he goes back to sleep. I don’t even know what to do at this point. I start his bedtime routine about 6:45 or 7. He gets a bath, lotion, massage, fresh pajamas, his sleep swaddle sac on, and he gets his final bottle for the night. Then he’s asleep by 8 or 8:30. He goes right to sleep but about midnight or 1am he begins waking through the night. Every single time it’s screaming and crying not just talking or babbling. Also, we use the Hatch sound machine at nap and nighttime. What else can I do or is he just a bad sleeper?

Through the day he eats 6oz every 3 hours and takes 2-3 naps that range from 1-2 hours each. I feel like I have done all the things and am just forever tired😭
