What do you think are the three best ways for parents to show their love and affection to their children? why are these the most effective ways to demonstrate love?

I think that by spending time with the child ,doing things that are fun to them, is one way for one to demonstrate their love to their child because the child might feel like you are listening to them. Another way would be to give them things they want. This may sound just like one is spoiling the child and bribing them for affection but this may actually mean, once again, that you are listening. And lastly, a way to demenstrate affection would be to just know the childs feelings and respectfully react because ones not all up in the childs face "hover".
