Hi. My baby boy is one n half months old. I m breastfeeding him but even after feeding he gets hungry n i feel my milk supply is less. I hv tried infant formula like similac , then felt like baby gt loose motion . doc suggested Isomil which is lactose free soy formula. Nw my baby s stool is coming green and wid a streaks of blood. I m worried as what caused dis.. And wch formula i shall feed him as top feed.
