My daughter Emma is also 6 months old. I began giving her solids when she was about 5 months.
At first I began with the good ol rice cereal which she loves. I then started adding pureed fruit to it. She was content with this for about the first month. After speaking with the CAFHS nurse, she suggest I start giving her a solids meal for dinner before her last bottle and so we did.
Emma now has her cereal, or fruit, or a combination of both for breakfast before her first bottle, and then for dinner before her last bottle she is having another meal of solids, usually something like pumpkin and sweetcorn, or lamb and vegetables from the Heinz range. She quite happily gobbles down the whole jar full and would probably eat more if I let her.
Having the extra solid meal didnt affect her bottles either. She is still having her 4 bottles a day.
Hope this helps.
