Baby turning yellow to orange while sleeping

Hi mommies! Anyone with same experience po. Woke up and saw my baby turning yellow tapos nung binuhat ko bumalik yung kulay niya. Then my time din na orange yung kulay niya pag gising ko tapos iiyak , ganun din binuhat ko bumalik din yung kulay niya. Shared this with my mother in law and pinsan ng asawa ko. Namalikmata lang daw ako. Pero I saw what I saw. #advicepls #firstbaby #theasianparentph #1stimemom
