You totally don't need to be worried. Many bf babies aren't interested in solids until nearer 12 months. All this means is that your bm is giving her everything she needs. Nice to know hey! My first DS was the same, he had no interest in solids at all until 8 or 9 months, and was over 1 before he ate well. Now he is a really good eater. FWIW, I think I made his eating worse by trying so hard to get him to eat. If I had my time over I would only offer it once every week or two until he showed interest.

Remember that milk is the most important food until 12 months. Before that age is just about learning texture and taste. She will eat when she needs it.
