8 week leap - help!!

Hi all - we are a little behind y’all as my LO was born 2-28. I read a lot about the 8 week leap. As the clock struck midnight 2 nights ago basically my LO basically stopped sleeping except for a half hr after feeds when we hold him up for reflux. He is 8 weeks 1 day. My husband and I are losing it as he is back to work and I am home alone w the baby during the day. Nighttime is the worst. We have a routine of bath time , story and feed which we try to wrap up by 8 or 9 but it’s been taking an hr to get him to sleep and then he’s up in 1-2 hrs. And repeat thru the rest of the night. He’s got a swaddle, sound machine, dark curtains. Any other tips?? Very emotional and tired over here!!
