Have been giving mixed feedings to my 3 month babe due to low supply plus frequent visit to polyclinic or hospitalization for jaundice. Had cut down alot on formula after she turned 1 month (couldn't cut out formula fully cos she'll have signs of dehydration after a couple of days fully breastfeed) and breastfeed more often. Turned to a LC for help but only help in achieving a deeper latch. Tried lots of milk boosters but I seems to be immune to it. I realized the more I breastfeed, the more fatigue I am and I tends to sleep more. Is it normal? Babe also latch longer and use my breasts as human pacifier.
