My baby is 4months old and 50% formula, 50%Breastmilk. I decided to switch to hipp organic milk since it is organic and the last formula she took caused her constipated for 2 days. Since I started hipp, she is no longer struggling to poop. Now, i am taking carica malunggay capsule to increase my milk supply and so far (2 days), from 4oz, I already got 7oz every 4hrs pumping. By the way, may baby does not latch directly to nip, so I believe that is the primary reason why my BM supply decreased.
