Although each child will follow a sequence of milestones throughout their development, the rate at which they reach those milestones may differ between each individual.
Development is broken down into a series of age groups:-
0 - 3 years
3 - 7 years
7 - 12 years
12 - 19 years
These development rates are guides based on various research undertaken.
A child's physical development increases the most between 0 - 3 years. As a baby between 0-3 months they go from being only able to move their hands, arms and legs in a limited movement, to by the age of 3 years being able to run, have hand co-ordination i.e. throwing balls etc.
Social and emotional development is slower, with interaction with adults slowly building up i.e. recognition of mother/father in the first few months, but by 12 months, they will have show affection to carers, although be wary of strangers. Generally during the latter stage of this development they will start to have a sense of self and independence including impulsiveness by the age of 3.
The language development in this stage is slow - with only gurgles and babbling for the first few months, with laughter not really developing until 6-12 months. Together with intellectual development children between 2-3 years should be able to put together a simple sentence of words, ask questions and even scribble & mark paper with pencils and crayons.
The sequence of development, as earlier mentioned, differs from child to child. In the 0 - 3 years category, a baby may have developed stronger neck muscles earlier so can hold up its head within a few weeks, others may take longer. Other physical examples are with crawling and walking. Some children will continue to crawl until they are 15 months before they take their first steps, whilst others may commence those early steps at 11-12 months.
The majority of children, unless
