I'm pumping my breast milk and bottle feeding my baby. But sometimes I can't get enough or maybe not in time for her before she gets hungry and fussy. So I suppliment. Maybe 2 to 4 oz of Enfamil usually at night 🌙. I don't like giving her the Enfamil because it makes her more fussy and she strains and grunts and cries more. Should I be doing something differently. I've tried to just pump pump pump until I cant take it anymore but its still not enough. Any suggestions?
