The 16 Hindu Samskaras)
In the case of an adopted child, items 1 to 3 cannot be done and these get supplanted by the adoption ceremony done according to the scriptures/sastras. If the adoption was only civil (i.e., as per the secular law) then pl. consult your vadhyar as to whether an adoption ceremony as per sastras/scriptures is necessary. The vadhyar may dispense with this but then the adoption will remain "asAstric" and hence invalid from the religious pov. You may get confirmation about this from Kanchi/Sringeri or any other head of a matham.
Scriptures/Sastras permit complete haircut only after upanayanam. Only Choodaakaranam (also referred to as "chowLam") is allowed as per sastras, before that.
Items 4 to 9 will have to be performed before the Upanayanam, on that day itself if these vaideeka samskaras have not been done for the adopted boy in the prescribed time.
