I have 3 kids 5 7 and 9. They all have been envolved in our renos and the whole process of buying, renting and adding value. My 9 year old liked the show house rules ( I hate it, no budget and helpful tradies). So she wanted to do a before and after. Gave her some paint and said off you go. Before and after. Nothing special but she loved the experience. The house we just purchased is a mess and she has already a list of what she wants to do.
