When I'm feeding my daughter there's a pain in my back is that normal?

Thank you ladies sorry been so busy... I did get it under control I use extra pillows.

try laying on your side to feed your baby, it's comfortable and a lot easier on your back

are u positioned correctly? try a boppy and extra pillows

your posture may be wrong. I have an old injury from 2 car accidents and since breastfeeding my back pain has been on 10:(
