As part of the learning process, children need to have time to form new pathways in the brain to interpret, comprehend and perform new skills. And adults need even more time to adapt to new skills because of pathways they have already embedded.
Consider what it must be like for a child, particularly young children who are still trying to work out how their bodies work and are still developing their motor skills. Sometimes it may seem as though they are not progressing and even that skills are deteriorating but this is normal while they are experimenting and learning new concepts. Depending on the child, progression may take anywhere from a few weeks to several months, but it is important to be patient and supportive during this process so that the child does not lose interest or confidence while developing at their own pace.
