Cooking oil is plant, animal, or synthetic fat used in frying, baking, and other types of cooking. It is also used in food preparation and flavouring not involving heat, such as salad dressings and bread dips, and in this sense might be more accurately termed edible oil.
The American Academy of Pediatrics currently (2012) recommends: The American Academy of Pediatrics reaffirms its recommendation of exclusive breastfeeding for about 6 months, followed by continued breastfeeding as complementary foods are introduced, with continuation of breastfeeding for 1 year or longer as mutually desired by mother and infant..
The WHO recommends only breastmilk for the first 12 months and then continued breastfeeding with supplemental food until 24 months. This is because of the great benefits for the health of the baby. My son is 16 months and I am not planning on weaning yet. I hope that he will want to wean around the two year mark.
