The Sequence of and the Rate of Development Why Is It Important to Understand This Difference
Samantha Larvin CPY 3. 1 – Understanding child and young person’s development. Explain the sequence and rate of each aspect of development from birth to 19 years. NEW BORN BABY Physical – The first few days of a baby’s life are usually composed of long periods of sleep interspersed with short periods when the baby is awake. The duration of wakefulness lengthens gradually and includes periods of fretfulness, crying and calmness. The responsiveness of the baby depends on the state of sleep or wakefulness (Brazelton and Nugent 1995).
At birth the arms and legs are characterisitically stiff (hypertonia) and the trunk and neck floppy (hypotonia). Lying on the back (supine) the arms and legs are kept semiflexed and the posture is symmetrical. Babies born after breech presentation usually keep their legs extended. Pulled to sitting, marked head lag is present. Held in a sitting position, the back is curved and the head falls forward. Placed on the abdonmen (prone) the head is promptly turned sideways. The buttocks are humped up, with the knees tucked under the abdonmen. The arms are close to the chest with the elbows fully flexed.

Social, emotional and behavioural – At this stage the self esteem of children and young people can be very vulnerable, their bodies will be taking on the outer signs of adulthood but they will still need guidance in many different ways, they will want to be independent of adults and spend more time with friends of their own age, but can continue to display childish behaviour. It is particularly important to teenagers that they feel good about themselves and want to belong.

They will lack experience and individuals will vary in emotional maturity and the way in which they interact with others. Moral – B. Explain the difference between: The sequence of and the rate of development: Each child is unique and will develop at their own rate, while they usually follow the same pattern of development the ages at which they reach them may vary.
Milestones of development are given as a broad average of when children may be expected to attain a particular stage. You may notice in particular classes or year groups, some children may stand out as they have reached milestones earlier or later than other children. Sometimes if children’s growth patterns are very different from their peers this may have an effect on their behaviour. For example children in the last two years of primary school may become taller and develop some of the first signs of puberty.
Girls in particular can become much taller than boys and this can put pressure on them to behave differently. There may need to be additional provision made in these cases for example when getting changed to PE there may also be pupils who are very tall or very small for their age and this can sometimes affect how they are treated by their peers. It can also affect social and emotional development. The patterns of development discussed here should therefore be seen as a guide to help you draw up an overall idea of these different stages. Why is it important to understand this difference:
