dear sreevani ,
surely i will tell you how to do, the procedure was told by our family pujari..chant this mantra for 108 times daily for 90 days without having anything early in the morning.. place a bal gopal photo or if u have an idol that will more nice, u can also continue after that till u get positive results.. keep any prasadam daily like mishri.
i wish u also all the best and baba bless u with a healthy child as expected.
om sai ram
