Milestones or furlongstones?
A study was carried out over five years of 15000 children aged between one day and three months. It was observed that many infants passed their important 'milestones' much earlier than is suggested in present textbooks. A plea is made for discarding the traditional ages for the various landmarks in the development of a child. The changes of mental development are very important in the first three months and during the three to six months period the baby seems to be merely consolidating more methodically what he was doing less conveniently during the first three months.
