self soothing help

Alicia
Hi mums! My daughter is 5.5 months old & at the moment is still being fed to sleep for naps and bedtime. We were going to start sleep training (the sleep wave method) but have decided to wait until she is 6 months. However I'm exhausted. She's waking so much at night & it's clear it's bc she needs me to get her back to sleep. She has 2 big feeds in the night which she has always done but all the others, she nurses for less than 5 minutes and is asleep again. Does anyone have any tips on helping her to learn to self soothe? I'm not trying to wean her night feeds as I don't mind the 2 that she normally has. I'm not getting much sleep & I love my sleep 😩
