Wa'alaikumassalam sis! Ahhh I feel you, my eldest was the same, gigit je diam je, pastu dah rabak je notice! Honestly for baby at 8 months, I'd suggest stick to gentle options like vitamin E oil or pure coconut oil dulu, dab-dab aje on the marks, sebab kulit baby still sensitive. A few of us mums tried silicone-based scar sheets (pakai during the day under clothes) and they do help flatten the marks over time, but make sure it's baby-safe. The good news is most of these marks will fade on their own as baby grows, tapi consistency is key, apply regularly lah. Dalam meantime, most important is the prevention: mosquito net over the crib, light long sleeves when it's not too hot, and maybe ask your pediatrician about safe insect repellent untuk babies
