At the next stage, swim aids will be removed in stages.
The pupil has to reestablished their balance and co-ordination in the water. This can take time and patience from both child and parents.
All children are difference, so they all take different lengths of time to learn.
Some children take to breast stroke easily yet may hate putting their face in the water; others may live under the water but may not feel confident on their back.
So it is best never to compare one child to another. Even siblings!!
When good co-ordination has been achieved, for breast stroke, back stroke and front crawl over the distance of 5m without out aids; the child will move to the next level.
If you continue swimming at the same time as lessons, confidence grows and swimming will become enjoyable and more relaxed. Children then achieve more!
