Normally when my kids are in trouble or just out of the blue I say to them; I love you knotty or nice; and give them a kiss on their head or smile. Also at the end of a sharp disagreement, I try to end by letting them know I love them; if they are angry at the end of our disagrement, sometimes they don't say I love you back. Whenever they do not respond, I tell them that no matter how they feel they should say I love you back; although they may not like me at the moment, that doesn't have to stop them from loving me. Eventually they say it reluctantly but they say it. The reason I do this is because I want my children to learn that even if we don't like someone at the moment we can still love them.
My son Raul show me that if I consistenly show my kids the way they shall go, they will imitate it.
Peace our bichon poodle sometimes humps his toy and as you can imagine it creates an erection that causes him to have a very hard time walking (sorry for the graphic description, but not everyone have a male dog). The kids get grossed out every time it happens.
One day Raul came home from school and found Peace unable to walk to him due to his uncomfortable state. Peace tried to walk to greet him but he was very slow. Raul upon noticing said; "Ahh! Peace this is how you greet me" and started to walk away. Within seconds of walking away, Raul turned around and did something that melted my heart, he said; "I am going to pet him because even though he is gross right now I want him to know I love him no matter what he looks like". He pet Peace and then walk away saying; "eww! and went wash his hands" I said son that is awesome.
Maybe there will be things our children will not follow but there are things they will.
"If a child is trained up in the right way, even when he is old he will not be turned away from it"
Proverbs 22:6 from the Basic English Bible
