Hello everyone! I gave birth on September 27th to a girl. I almost fainted today because of panic and not knowing what to do. My daughter was drooling, couldn't swallow the saliva and from that she was arching her back. A scary sight. The nurse said it happens sometimes, just wipe with a diaper cloth the saliva in the mouth. Here is my question, is this normal? What can I do so that this doesn't happen again, God forbid it will happen when I am sleeping or not nearby.
