is breast milk more or less filing than formula?

you're very welcome!! (:

Thank you all @brynskye430 @queeneden @tahtahme

they are both filling... but Ypu have to breast feed more because it digests quickly.

same, breastmilk just requires more often to feed because it goes through their body faster, formula sits in the stomach like an hour or two longer. but both satisfy

Same. But because it's designed specifically for your baby, it's digested faster.
