Newborn Jaundice

Hi mga mommy and daddy. First time parent kami ni wifey, nag give birth sya sa baby girl namin nitong May 9. Normal delivery and okay nman si baby, naconfine sya sa NICU ng 3days dhl under fed si baby nung 1st day wla ksing lmlbas na gatas ky mommy. Phinototherapy si baby for 3days, nung inuwi namin mejo madilaw pa dn. Ngayon naman unti unti ng nwwla pero nannilaw pdn. Pure breastfeeding lng kme, okay naman si baby active, masiba dumede, normal na wiwi and 2-3poops per day. May dapat ba kaming ika worry? hanggang kelan po ba naninlaw ang new born pg breastfed? Yung pedia kasi namin pasimpleng inuudyok na mag formula kami kaya lang breastfeeding advocate kami ni misis kya gsto nmen mbgay ung exclusive breastfeeding.
