Please do not expect your child to make equal and constant progress every swimming lesson. Learning to swim is not the easiest of accomplishments for all children. In particular the breathing technique can be especially difficult and may take several swimming lessons before the swimmer can master it.
It is common for children to appear to make no progress at all at some stage, in fact they may even regress for several swimming lessons. Please be patient, it will not be for want of trying by the swimming instructors and they understand it is part of the process in learning to swim. Parents should try not to convey anxiety over this to their child. All our swimmers learn to swim; some make rapid progress, some take longer!
Your enthusiasm and support for their effort is important as they learn to swim.
