Feeding 6 Months Old BB Rae

I ve started Bb Rae with semi solid since she was 5+ months old. I started with white rice cereal mix with my breast milk and she enjoyed very much. When she turned 6 months, I started to give her home made puree like broccoli with potatoes, sweet potatoes with carrot, pumpkin with sweet corn. I also give her fresh fruits like papaya, banana, pear, apple, avocado, golden kiwi, orange. I had tried giving her home cooked porridge but she doesn't seem to enjoy. Now I d feed her puree for lunch, 2 teaspoon of cereal and fresh fruits for dinner. My bb still prefers milk than solid, so the portion I give her is pretty small as she still latch on for milk 6 to 7 times a day. I was shocked when 1 mommy friend told me that she fed her 4 months old bb commercial cheesecake, yummy yogurt sold from counter, yakult etc. She is aware of the high sugar content but she thinks the goodness of those food outlay the bads. Don't she realized these r processed food high in sugar and other addictives which may be bad for bb internal organs like liver, kidney, digestive system etc as they r newly formed? Also bb may get addicted to sweet or salty taste and as they grow they may yearn for more sugar or salt and turn into a fussy eater! No I didn't confront this mommy as I think she is an adult and a Mother herself, so she can decide what is best for her own bb. She is responsible for her action, be it Good or Bad! If bb ever gets sick, we all know who will suffer!!
