At that age, DD would have a feed in bed with me first, then breakfast about and hour or so later.
Small portions, more often, and alternate them with BM, but avoid giving her a feed BEFORE a main meal. Offer the breast after the meal if she is done eating (not necessarily finishing the portion, but finished eating itms).

But they don't eat much anyway... You will find she will have days or even meals, where she eats like a horse, only to pick like a bird the next day. Don't stress - so long as the nappies are consistent and she isn't dropping weight, all is well and she will not let herself starve. You are doing fine
