i usually give about slightly more than half bowl of puree for my baby's lunch and dinner. It also depend on how much milk intake baby had taken. My baby is a big eater. He would whine and cry if he was not given enough. He managed to finish the porridge puree each time he was fed.
It depends on your child food intake. I would give about half a bowl of the size of an IKEA bowl. He would finish those and asked for finger food shortly after meal.
