At 6 months of age you don't need to worry about Her getting enough "solids" as her intake of milk will be giving her the nutrition that she needs. Giving her those finger foods or doing some BLW as suggested is awesome to try in the meantime.
Is she teething right now? DS2 is 7.5 months old and was a champ with solids, but currently on a spoon strike, which is probably because he is teething, so I have been giving him sticks of celery, cucumber, apples, mango etc. As well he loves to chomp on some rusks I made the other day. There isn't anything I can do to get that spoon in his mouth, so using the opportunity to explore some finger foods!!
HTH!
