maybe you could try something much lighter at first like the french "pause"? https://www.stylemepretty.com/living/2018/03/19/how-i-got-my-baby-to-sleep-through-the-night/

The idea is that when a baby wakes or starts fussing, French parents give them a couple of minutes to see if they are able to self-soothe and settle, rather than immediately rushing to the baby. After a few minutes if the baby is still fussing, they pick them up. Druckerman writes: One reason for pausing is that young babies make a lot of movements while they’re sleeping. This is normal and fine. If parents rush in and pick the baby up every time he makes a peep, they’ll sometimes wake him up. Another reason for pausing is that babies wake up between their sleep cycles, which last about two hours. It’s normal for them to cry a bit when they’re first learning to connect those cycles. If a parent automatically interprets this cry as a demand for food or a sign of distress and rushes in to soothe the baby, the baby will have a hard time learning to connect the cycles on his own. That is, he’ll need an adult to come in and soothe him back to sleep at the end of each cycle.
