Is Jelly-like/sticky poop normal for fully breastfed 17wk old baby?

No, it is not normal for a 17-week-old breastfed baby to have sticky, jelly-like poop. This type of poop may indicate a digestive issue, infection, or an allergic reaction. If your baby's poop appears to be jelly-like and sticky, it is important to speak with your baby's pediatrician for further evaluation.
