not wishing to go off topic too much jim but yes when family allowance started it was not given to the first child born however a few years later it was given to all children
Family allowances were introduced in 1946, with the first payments being made on 6 August. At that time, they were only paid for the second child onwards, a further watering down of Beveridge’s scheme. In 1952, the Conservative government reduced food subsidy, which had been in place since the war. From October 1952, family allowance was increased by three shillings per week in order to advance the potential effect on nutrition. As a means of encouraging families to keep children in education, the Family Allowances Act of 1956 extended the family allowance to all school children, although the bread subsidy was abolished. In 1961, Cabinet agreed that the majority of apprentices be excluded from the family allowance provisions, but dismissed proposals that family allowance for the second child be abolished. Family allowance provisions therefore remained intact in the Family Allowances and National Insurance Act of 1962.
