Hello everyone. Girls, my daughter often chokes on spit, sometimes it rips her with milk and runs through her mouth and nose, I cry every time after that, afraid she'll drown. I grab her in a vertical position, slap her back, thank God it helps, but I'm scared suddenly something will get stuck in her nose with milk, what should I do in such situations? Nothing specific is written online, has anyone experienced this, is it normal and how should one behave in such a situation?
