I offer 3 or 4 solid meals a day, and DS has around 7 bf's as well. He's 9 months old. Sometimes he'll scoff all the food, othertimes he'll turn up his nose and just want bf. My MCHN has no real concerns with him - she wants me to keep offering lots of different foods, and he'll work it out for himself.

I would offer J small amounts of solids reasonably often and see how she goes. If in a few months she's not eating well then maybe get concerned!
