@Evie is there a number for this or is it for your area specifically? X
My left side has always produced a lot less than my right mostly because her latch has always been worse on that side. I used to give her both sides every time she nursed and primarily the left over night but now I only do it in the morning & before bed. My right side increased for what she needed since she was on it more. Maybe try a different position? My daughter only really does well on my left side when we’re laying down, otherwise it takes her awhile before the milk comes out. Good luck!
I would suggest calling the breastfeeding helpline I called them this morning over a few things and they were amazing! Really informative and just amazing! Xx
