This is from my mom told me- from her experience with me.
After I was born and was taken back from the hospital, I sleep throughout the day time. But as soon as the sun sets- I started crying throughout the night.
According to olden beliefs, if the baby proceeded to cry after one month (after the baby full moon), it will last for about 100 days in total.
My grandaunt, who was taking care of me was at her wits end as to what to do. She went and approached her friend who shared with her this bizarre method- sweep the rubbish from the corners of your house. Put in a place and burn them during sundown- it is just a very small fire. Then carefully hover the baby over it (okay must be very careful as this is fire)….and she would be able to sleep soundly.
This strange method seemed to have worked….for a few days. After that, I continue to cry again.
However, I would recommend to check with the doctor. If there is no cause for concern- means no health issues….. then hold the baby in your arms, close your eyes, calm yourself and say some sincere prayers- to ask for protection for your child based on your faith.
