My baby started getting like a rash in her face and now all her face if full of bumps and behind her ear on her hair... I'm scare i don't know what it is ... if we go out the heat irritate them and gets super red... I took her to the pediatric and they didn't even bother on looking at them and just answered oh it normal... they don't seem normal to me! 😞😕
