How do you keep your baby's diet balanced?

My 8.5 months old baby gets fruit puree as well as porridge blended with vegetables and meat and topped with whitebait powder for her 2 daily meals. For puree, she has tried avocado, apple, pear, pumpkin, rockmelon, banana, papaya... for her porridge, usually there will be 2 types of vegetables like broccoli, cauliflower, spinach, or pumpkin, carrot, and either chicken or pork, and egg. Whitebait powder is to give her added boost in DHA, calcium and protein.
