MK: Dear Guruji, you have mentioned that garbhadan sanskar means mantras are making the best pious effect on the chitta of husband and wife; As a result, good child is achieved. So without the above sanskar, good child cannot be obtained? Due to the lack of Vedic knowledge I have missed this sanskar earlier before my son was born, can it be done later? If yes, when should I get it done? Thanks!
