Child development means progressive, orderly, acquisition of skills and abilities of a child as he/she grows. This developmental activity is influence by a lot of things including genetic, neurological, physical, environmental and emotional factors. Developmental assessment is very important for a child especially from the day he/she was born until 5 years old. If there is any sign of developmental delay, prompt management should be sought. Observe your child at home, if there is anything that worries you, do not hesitate to ask your physician opinion about it.

During developmental assessment, it is important to make sure that the child is cooperates, not fretful, too tired or hungry. He/she should be in a good health. This simple measure may look simple but it can affect their assessment tremendously. If the child is a premature baby, full allowance should be given till he/she is up to 2 years old. The parents are almost always right that is why their opinion is important. If the parents claim that the child has squint, there is high possibility that the child has squint.

Normal developmental progress is highly dependent on the integrity of child’s hearing and vision. That is one big reason why hearing and vision assessment has become 2 important aspects in assessing a child. This means that a normal pattern of speech and language development is essential for a normal social, intellectual and emotional development. Important to note that if the child has advanced motor development, it does not mean that he/she has mental superiority like some people think might be possible. However, manipulative skills can be used and can be a more reliable guide. Assessment of social, gross and fine motor skills are also important.

Developmental retardation may be global and affect all areas equally. Sometimes it can be normal except in one specific area for example in speech. If this occurs, deafness should be excluded. In global retardation, hypothyroidism should be ruled out in all cases. Below is a list of warning signs of the developmental progress.

Developmental milestones are a set of functional skills or tasks that most children can do at a certain age range. It has a lot of individual variations. Some children can achieve their milestones earlier than others. Delay in one part doesn’t mean anything. You have to see the big picture before saying that your child is abnormal.

Check your child’s developmental progress using following tables. Should you see significant delays in any of the parts, seek your physician’s advice. Your child might suffer for developmental delay. The earlier action taken gives better benefit to your child.

The part two consists of hearing, language and social behaviour development. Please read part one of the articles that provide you the information about physical skills (gross motor), vision and fine motor development of your child.
