Importance of play
Play is extremely important whilst children are growing up, and it helps prepare them for the future by equipping them with relevant skills and qualities. Vygotsky supports the idea that children are able to learn and develop through play, when adult support is given at the right level to the individual child. It is important that as practitioners, we do recognise that each child is an individual, which is vital in terms of play. For example, in order for a child to develop and learn through play the practitioner must not interfere in certain situations unless invited to do. 
Children will move through stages of play, according to Parten. These stages vary from observing other children, to playing alongside them, known as parallel play. This theory demonstrates that importance of play in all circumstances. 
Play enables children to express themselves in a way of which makes sense to them, as often children may find it difficult to find the words to explain and express how something which has happened in the past may have affected them. Often, children are able to process and make sense of these emotions through play, Freud agreed with this statement.
Moreover, play does not only help children develop and work towards their next steps, but it also has emotional benefits. Whilst playing, children often feel happy and are able to build bonds and relationships with those around them, it gives them the chance to take risks within a controlled environment. Overall, I believe that play is essential for children, as it gives them the freedom to be creative, whilst developing and learning in some situations.
