From Birth to Five Years, based on the pioneering work of Mary Sheridan, is widely regarded as the go-to reference for health, education and social care professionals, or anyone concerned with the developmental progress of pre-school children.

In this new fourth edition, the text has been developed to further align it with current child development philosophies and practices, and to support the wider group of professionals that are now required to take steps for promoting children's development as part of their assessment and management plans. This book aims to improve the clinical management of children with developmental disorders, through providing the full range of developmental attainments, methods of observation, and advice about when to seek help.

Features of this completely revised edition include:

• 
  
  

• For students and tutors – information on theoretical aspects of development, with further reading suggestions and references including the most recent international studies in the field

• 
  
  

• A new section on the development of attention and self-regulation

• 
  
  

• Contemporary case studies with guidance on when to raise concerns for students and teachers

• 
  
  

• Discussion points to stimulate class debate

To complement this book, a new companion volume, From Birth to Five Years: Practical Developmental Examination, offers a step-by-step 'how to' guide, including guidance on enquiry and observation, how to chart typical and atypical patterns, and 'red flags' for recognising significant delay or abnormality.

To consolidate and expand on the practical and theoretical information across both books, a new companion website is available at www.routledge.com/cw/sharma, which includes the following additional learning material:

• 
  
  

• An interactive timeline of the key developmental domains

• 
  
  

• Introductions to theory with links to further reading

• 
  
  

• Research summaries

• 
  
  

• Video clips demonstrating practical assessment skills

The Newborn Baby

The newborn comes to this world with a rich repertoire of motor and perceptual skills acquired in utero. These skills enable the newborn to start a secure attachment and continuing reciprocal relationship with caregivers, and learn about them and the environment. Observing the neurodevelopmental status of the newborn provides a window into the health of the antenatal process, reassures parents and helps establish a basis for observing future progress.

Alertness and responsiveness

During the first few days of life, there is a great variability in the behaviour of babies depending not only upon the baby's maturity and physical condition but also upon its state of alertness or drowsiness, hunger or satiation.

• 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).

Posture and large movements

• At birth, due to weak muscles, movements are mainly limited to arms and legs. The muscle tone is increased in the limbs and decreased in trunk and neck — when pulled to sitting, marked head lag is present and in a supported sitting position, the back is curved, and the head falls forward.
• Arms and legs are kept semi-flexed when lying on back (supine). However, babies born after breech presentation usually keep their legs extended.
• When the infant is held in ventral suspension, the head drops below the plane of the body, and the arms and legs are kept partly flexed.
• In prone position (on the abdomen), the head is promptly turned sideways. The buttocks are humped up, with the knees tucked under the abdomen. The arms are close to the chest with the elbows fully flexed.

The primitive reflexes

Primitive reflexes are complex automatic movement patterns, generated by the lower brain (brainstem). They commence as early as 25th week gestation and are fully present at birth in term infants. They become more and more difficult to elicit over the coming months as cortical inhibition emerges and protective postural reactions begin to appear. Persistence and asymmetry of primitive reflexes may indicate an underlying neurological impairment.

• The Moro reflex is the best known of all the primitive reflexes. It can be produced in several ways. The usual method is by sudden, slight (2.5 centimetres) dropping of the examiner's hand supporting the baby's head. The response consists of symmetrical wide abduction of the arms and opening of the hands. Within moments, the arms come together again, simulating an embrace. The reflex fades rapidly and is not normally present after 6 months of age.
• Reflex rooting and sucking behaviour is apparent unless the baby has just been fed. Infants show nutritive sucking for feeding and non-nutritive sucking patterns (self-calming on fingers or dummies). Rooting fades by 6 months and involuntary sucking by 12 months.
• Protective gag and cough reflexes are also present, and these persist throughout life.
• Strong and symmetrical palmar grasp reflex is present but fades rapidly over the next 4 to 5 months.
• Reflex standing and reflex walking are apparent during the early weeks of life if the feet are placed on a firm surface.

Hearing and vision

• Babies are sensitive to light and sound at birth though visual responsiveness varies. From birth onwards, or within a few days, infants turn their eyes towards a large and diffuse source of light and close their eyes to sudden bright light. Infants show a preference for looking at faces or patterns. Visual acuity is poor at birth (20/200), rapidly reaching adult values of 20/20 by the end of first year. An object or face must be brought to a distance of 30 centimetres to obtain interest and fixation. Infants usually turn their eyes to slowly follow a face.
• Infants can hear sounds in the last few months of pregnancy and show recognition of the mother's voice and of their native language soon after birth.
• The startle reaction to sudden loud sounds is present. Eyes may be turned towards a nearby source of continued sound, such as a voiced ‘ah-ah’ or a bell. Momentary stilling to weaker, continuous sounds is also seen.

Touch, smell and taste

Babies are particularly sensitive to touch on the mouth, face, hands, soles and abdomen. Stroking, rubbing and skin-to-skin contact is the human equivalent to licking in other primates. There is evidence that skin-to-skin contact between the newborn and the mother in the immediate postpartum period may have positive effects on breastfeeding success and on maternal blood pressure and cortisol levels.

Newborns recognise the mother by her smell. They show a smile-like response (tongue protrusion, lip smacking, lip sucking) to sweetened solution — it also calms them and reduces their heart rate, but they purse their lips after being given a sour solution.

Social interaction

• Within a few days of birth, infants establish interaction with their carers through eye contact, spontaneous or imitative facial gestures (protruding their tongue or pouting their mouth) and modulation of their sleep-wakefulness state. They show some recognition of their mother's smell and voice by becoming more relaxed, settled and happy.
