HA or HW milk

Hi mga mommies. Hope someone can give advice. My baby has atopic dermatitis which means need nya ng hypoallergenic milk (hydralyzed whey) Me and my partner both work pero ang hirap ng buhay at di ata namin kaya i-maintain ang gatas ni baby (S26 HA) Hingi sana ako advice is may alam kayong mas murang formula milk for this. My baby is 4 month old and unfortunately wala ako gatas... Thanks #advice #adviceaccepted #milkformula
