What do you give her? Purees? Finger foods? She may be bored with purees or not ready for finger foods. I'd say it's still in the realm of normal, as long as she's still drinking enough milk. They're still learning about solids at 8 months (esp if you didn't introduce them until 6 months).
I gave up on the purees except for the fruity ones with grains. My LO started gagging and refusing them. Gave her chopped up chicken and she loved it
My first baby LOVED like literally every puree I put in front of him. Then my second came along and he hated EVERYTHING! He'd eat a little for my dh, but NEVER me. I knew I was holding out and he wanted breast milk, not food. It stressed me out. I worried so much. BUT breastmilk was all he really needed and he did fine. He never actually ever had or like purees ever. He just held out until he was able to feed himself bits of real people food. I think he was 10 or 11 months before he ever liked food.
Really, this is SO normal. Don't worry, don't stress, just offer from time to time, but never pressure and he'll be just fine!!!
