A child may have a disability, such as down’s syndrome. This means that they may have an impairment of cognitive ability and physical growth so they will need extra support in daily activities and activities at nursery. They also have different facial characteristics which can lead to bullying and low self esteem which can mean they may not want to go to school, or feeling as though they cannot concentrate because they feel self conscious. Another health factor could be cerebral palsy is a non-progressive non-contagious disability which is also developed at birth due to the brain. This affects motor conditions that cause physical disability in human development, resulting limits in movement and posture. Children who suffer with this may be held back years in nursery and schools because of their lack of movement and can miss out on trips which other children are going on. Other health factors which could influence young peoples development could include asthma which will affect the child’s breathing. Children may get breathless taking part in physical activities and will have to use an inhaler to open the airway. Also, a child may be born with a sight or hearing impairment which affects most areas of the child’s development. If a child is unable to see, they may not have had the opportunity to join in with physical activities, such as running or football, therefore they may be lacking in this area. If a child is deaf, they may not be able to communicate accurately to other people so will have little social skills, so they could find it hard to make friends or have a connection with their teachers. Learning difficulties are also a factor that influences a child’s development. Children with learning difficulties will need extra support with certain areas of development and may develop a low self-esteem because they get annoyed with themselves for not being able to do something, such as a simple maths problem, or read a book.
