Eh normal lah tu, especially kalau anak makan makanan yang berminyak or kalau weather panas, najis memang boleh melekit dan licin macam tu! A few of us tried using warm water first to rinse, then gentle sabun, and memang better. Tapi kalau najis dia consistently licin macam oily or macam ada problem, maybe worth checking dengan pediatrician just to be sure semuanya okay dengan digestive system dia. Biasanya fine je, tapi better safe la
