Fixed Mezuzos

One of the Mezuzos in someone’s house fell down. When the rabbi came to his house to take care of it, he realized that there were more issues with Mezuzos – two doorways didn’t have Mezuzos, and one door had a non-Kosher Mezuzah. They fixed all the issues. Once all the Mezuzos in their house were as they should be, their daughter, who had been delayed in speaking, began to speak!
