10 month old wants to nurse all day

I’m honestly not sure what’s going on anymore. It seems like the last 2 months my baby has wanted to comfort nurse 24/7. We cosleep so she quite literally eats all night and all day. During the day her actual feeds are around 5-10 minutes but recently she will switch from boob to boob ALL. DAY. LONG. At first I thought it was teething pain. She did get 3 teeth in the last month but now I don’t see anymore coming in. She gets so frustrated when milk comes out and she’s full. Any ideas on what is causing this? I know I make more than she eats so not a supply issue. It’s really starting to make me hate breastfeeding and it’s sad because I loved it up until this point. I’ve started refusing her and trying to distract her but it doesn’t last long. HELP.
