milk supply dropped tremendously

you have to pump more regularly, 5 hrs apart is too long - I find, but of course understand its because of your work. If not working, you can breastfeed your child from 1 breast & right after pump tge other one. Try to incorporate oats into your diet, it works wonder for me! Drink more fluid & relax, dont be stress over this. If need to, supplement with formula..we turned out ok ( i'm sure most of us parents here were formula fed babies ). All e best!
