11MO eating very little solids

Hello mummies my baby girl refuse adults to feed her solids during meal times and recently I started BLW and she’s doing it happily but the intake is very little, a bowl of porridge she maybe ingest 3 spoons? The rest would be on the table or on the floor. I am afraid she doesn’t get enough solids in her body. She’s drinking well 240ml per time. But she’s only 8kg for 11MO. Anyone facing the same problem?
