Help plz! Desperate!

My 7m old still doesn’t sleep through the night he wakes up so many times at night. My first child was soooo easy. I’m so desperate for sleep! He’s on a routine and it still doesn’t work! He’s been on it since he was about 6w old. And he only takes 2 naps a day. One short one at around 11am then a long nap at 2pm that last til about 4-5pm.

I have tried everything to try and get him to sleep through the night and nothing is working! Please help me 😭😭😭😭😭
