Oh yes they really are, they are designed with this in mind and provides a really easy-to-use tools and once you get consistent with practising kindness and empowerment, you kids will ask for them!!!
It is entirely up to you what suits your family the best, there is no wrong or right way to use our products.
Here is a glimpse into what has worked well for our family; we use them when we first wake up in the morning, during breakfast time, in the car on our way to school, and then at dinner time has worked very well as it opens up for very meaningful conversations.
And then we also have used them just before be, which is really nice because we get to talk about our learnings during the day... For me, the single most important thing was choosing a time I could be consistent with.
