Normal je lah, terutama kalau minum formula, taik memang akan lebih melekat dan berminyak compared to breastfed babies. A few of my mum friends dengan babies on Lactogen pun cakap sama, especially dalam first few months. It'll change as dia grows and mula makan solid food, but for now just make sure you're changing nappy frequently so taik doesn't stay lama-lama on the skin, kasi gentle wash je.
