Boobs to soft to breastfeed

I’m frustrated with my boobs. breastfeeding is fine when there’s lots of milk but when he constantly wants to breastfeed and my breasts go soft theres an issue.

They get so soft he pulls the area around my areola in his mouth too and it hurts.

I’ve breastfed 3 babies and I gain a lot of weight during pregnancy and then shrink back down a lot so my skin is quite loose. I’m 3 weeks postpartum and noticed I only had a few days of sore boobs and engorgement and that’s it. When my other 2 babies I was sore and engorged for much longer.

I just hate the extra skin I have it’s so painful I already want to switch to bottles but I know a pump would pull at me to much too.
