mixing breast milk and formula ???

my daughter is 5 days old and im pumping and not really getting more than one ounce of breast milk so i put that in to her bottle and add formula and water to it to make it the 2 ounces she is suppose to eat...is it ok to formula and breastmilk feed...shes eating fine and holding it down and having perfect wet and dirty diapers...i heard it was ok to mix breast feeding and formula feeding i was just wondering if any other mommies were doing the same or if it was ok...thanks

Yes, it's fine

Perfectly fine.

It is fine to do but Karleigh wanted either one or the other. She wouldn't take it mixed together.
