our daughter (Dvorah bat rachel) has developed many health issues in the past year. We just had our mezuzot checked in March, but her health issues are getting more, her eyes and joints, and other organs are involved. my friend said there are rules we have to watch in the house to keep our mezuzot kosher. I do not know what are those rules. would you please guide me on the rules to follow at home, how to keep the mezuzot kosher. or what can we do to help her. How can I pray for her.
