7 Month Old Doesn't Like Food?

Maya
My daughter is 7 months old and we have given her rice, sweet potato, apple, banana, and spinach. We've been giving it to her in purée form for 3 days at a time and the only thing she hasn't refused is rice. She ate the sweet potato the first couple times and now refuses it. 
Has anyone else's baby done this? 
We don't know if we should stop trying to give her solids for a while or keep trying different foods
