LO still refusing solids?

My LO still refuses solids. He ate them for a few weeks around the 6 month mark and then just stopped! He has a pediatrician appointment coming up so I'll ask then but I'm curious if anyone is in the same boat? We've tried purées, cereal, and puffs. The puffs he will eat one or two of and others he totally refuses. He's EBF also.
