Do you offer group lessons?
On the whole the answer would be 'no' because each of us is so different. We generally find that one child may be more confident in one thing, other children will be more confident in other areas. But if a child is already lacking confidence and they are once again presented with a friend, sibling, peer that is better than them, it can reinforce that idea that everyone else is better than them. That they can't do it. They're stupid.
Also, we often learn differently so whilst 1 thing may work for you, for the other child, something entirely different would be more productive so the time spent isn't as effective as it should be.
You may choose to split the time and do half and half with each sibling, or alternate the weeks. However, group lessons are definitely not something we would advocate for.
Note: We are increasing the number of workshops that we are providing which would be presented for group work. If this is something you might be interested in, please do get in touch: [email protected]
