Just a couple of other thoughts Do you think she might be ready to stretch her bf therefore having the bf co-inside with solids? (This would allow her to get that little bit hungrier when feeds roll around) So you could try a 5min bf before solids, then finish off with however much she wants? Or on top of that or instead of that, maybe begin introducing 2 or 3 tblspns of solids at lunch as well in your current pattern but with the same deal, 5mins bf first then solids, concluding with bf from other side? (you could try this at the other feeds?) Does that make sense?

Again, these are just my thoughts love based on my own experience but as every bubby is different, this may not even work (and you may not even want to do this ) but I hth even a little bit
