Mislim da je "defekacija" a ne "defekcija"... i ako sam u pravu, onda bi ovo trebalo da bude dobar odgovor.

Evo i objašnjenja kakve veze ima sa neonatalnom žuticom:
How newborn jaundice is treated: If levels are elevated, you may be advised to expose your baby to sunlight (which helps to break down the bilirubin, making it easier for the body to eliminate) and feed her as often as possible to encourage frequent bowel movements (this will also help get rid of the excess bilirubin, which actually gives stool that brownish-yellowish color). In more severe cases, you may be required to bring your baby back to the hospital to spend some time under an ultraviolet light called a bili light.
