Good day everyone! I have a question, my child is crying suddenly. Right in the middle of nowhere. Usually happens when there are many people at home or someone goes to visit. And it can be nonstop for 15-30 minutes. They turn red and cry really hard. Although they're full, their diaper is clean. They said she had hypoxia. Is this related to that? I am very afraid.
