Hello Doc,,, My Daughter Is 43 Days Old..... She Takes

Hello doc,,, my daughter is 43 days old..... she takes her feeding very slowly... Our doc advised me to take calcimax plus of 2.5ml morn & eve... my baby likes that syrup... If i add that syrup with milk means she drunk well.... If not,, she never takes her feeding at all... So i add calcimax plus for all the time.....

My question is wheather i can add calcimax plus for all of her feeding ?.?.... And how much i should add ???
