Aww ang hirap talaga ng insect bites sa babies, lalo na pag nag-scar pa! Honestly, I'd suggest asking your pedia first kasi sensitive pa ang baby skin and baka may specific treatment sila. A few of us mums tried vitamin E oil or silicone-based scar products once cleared ng doctor, and it helped over time, pero dapat talaga validated muna ng pediatrician kung safe para sa age ng baby mo at kung gaano kalala ang scar. Patience lang talaga, yung iba sa friends ko noticed the marks faded significantly after a few months with consistent gentle care, kaya don't worry too much pa! Keep the area moisturized and protected from the sun din kung possible. Good luck, mommy!
