Definite answer the question from what age it is necessary to give to the child pair milk, is not present. Everything depends initially on quality of this most pair milk.
All authoritative pediatricians unanimously repeat that pair milk unambiguously before the use needs to be boiled. And when boiling all its useful properties, as well as harmful bacteria, disappear.
Spock and Komarovsky's opinions
Doctor Komarovsky about pair milk tells the following: "Pair milk contains many hormones which can influence early sexual development in girls and a delay of sexual development in boys". But nevertheless, according to doctor Komarovsky, you should not give milk to the child aged up to 2 years. Yes, in milk there are a lot of useful substances, and the basic from them calcium, but at it there are also such substances, for example, phosphorus which are very badly processed by a children's organism, and besides phosphorus directly influences digestion of calcium. Therefore, the your child is less on age, the worse than such steam room drink will affect a condition of his bones. The main issue at consumption of milk by the child is a quality of raw materials and amount of the milk drunk in day.
If the volume which the child drinks, is no more than 200 ml, such small dose will not affect negatively a stomach and bones of the kid.
Benjamin Spock considers that the child has to drink about 1 liter of milk a day. But it is not necessary to allow to drink it in pure form. That is it is possible to give to the child of cocoa, to cook porridges on milk, to do ice cream as the processed milk in any kind and in any food is already much better to be acquired by a children's organism because milk protein will not be present in pure form any more. And here pediatricians of the whole world do not recommend to drink cow's milk to children up to 2 years at all. It is the best of all to replace it with the adapted mixes with marking on bank 2 or 3 (from 6 months to 12, and the following for children is more senior than 12 months).
These mixes are as close as possible to female milk, and in addition at them still there are all necessary substances, vitamins and minerals which are necessary for the child at different stages of his life.
Advantage and harm of pair milk
Milk is useful because of high content in it of calcium, sodium, magnesium, potassium, phosphorus and other substances. But there is one biggest but which can turn all useful that is in pair milk in huge problems with health of the child - it is quality of milk. Yes, if eco-friendly food, full compliance with hygiene and sterility when milking cows was provided to cows, nobody would give them antibiotics, etc., milk, certainly, there would be 100% useful. But, much to regret of all parents, such ideal situation in the present world cannot be reached. Even the domestic cow who eats in the summer on meadows, and in the winter hay from this field will never give organic milk. There harmful bacteria will contain anyway, within 2 hours after a yield of milk milk will be the most useful, and here if not to put it during cold, the quantity of bacteria in it will begin to increase sharply.
