introducing solids yet?!

My baby will be 6 months old next week she currently takes the boop at night and bottle of breast milk with my husband when I'm at work. Our Pedatrician said we can start introducing solids to the baby but she just seems so not into it. She might take one or two bites and then just start having a fit. We tried sweet potatoes and another kind with same reaction. Should I keep trying or give her more time ?
