How should I feed my daughter...?

I'm a new mom & my daughter is about to be 5-6 months old and I'm starting her on baby food - I was wondering should I feed her baby food between bottles or when she has her bottle? She eats 3-4 bottles a day, about 7-8 oz. per feeding. I'm just a little confused if i should do it between bottle feedings or should i do it when she has a bottle... thanks!
