I do the same because otherwise she screams and wakes everyone up including the neighbours 😩
My 12 week old currently doesn’t wake through the night but when I hit the regression, I’ll absolutely be feeding back to sleep. I don’t have patience for rocking, and the boob works so well!
I think it’s whatever works for you but at the 4 month regression if babies are waking and feeding back to sleep it can become a bit of a viscous cycle which is hard to break. It can help to try and replace feed to sleep with another form of settling like patting/rocking as these may be easier to phase out later down the line. When the regression hits babies need to learn how to connect sleep cycles and ideally fall back asleep independently otherwise in some cases it can carry on for a long time x
Watching because I do the exact same. She genuinely seems hungry but starting to wake up even more sometimes every hour. She falls asleep on the boob after about 10 minutes and I put her back in the next to me. It's tiring!
