Can i feed my 12 month baby regular whole milk powder.

Depends: At 12 mo a kid can usually transition to a whole milk product. The use of any powdered product would require a dependable source of clean water for mixing. Unless this is readily available, all water should be boiled/cleaned of impurities before use in any dietary product. Use also assumes a diverse diet including other foods and a limit to 16-24 oz milk/day.
