At 10 months it really doesn't matter which you do - or even a blend of both. Experiment and see what works - if solids first helps her sleep then do that at dinner time!
At this age you may also find that separating the BF and the food works too - something like wake up - bf - play - brekky - snooze?- bf and so on.
As long as your bub is trying foods, mostly happy and growing then all is well.
