I don't know how it is called in English but it's something like an unintentional hex on the baby of some people. It is called "usog" in our language. When a person has that personality, he can put a hex on a baby when he take notice of the baby. For example, the person liked the smiling or laughing baby that he will play with the baby for a while. And when the baby goes home, he will be crying because he may be looking for the person. It's hard to explain, sorry. But the remedy is for the person to bless the baby with a drop of his saliva and the baby will stop crying.
