When you say "milk," do you mean formula? Or breastmilk? Or are you giving her cow's milk?
At 8 months old I was of the opinion that babies should still be having either formula, or breastmilk every 2-4 hours -- at least.
Her weight sounds like it's in a good place to me, so good job! If you get some more formula or breastmilk bottles into her routine, I think what you're doing will be perfect for your baby! I'd cut the juice though ... or at least only give it to her every once in a while -- as a treat.
