In our home, we're a pretty emotionally-attached bunch. I'm sure we're not alone in this, but we are very open with our affections, both me and the hubby and us with the boys. The boys are therefore very comfortable with hugging and yes, even kissing their friends goodbye. (This was quite something for their friends to get to used to at first.) I'm sure there will come a time when we'll have to curb this activity, but for now, I'm not worried about it.
One of the phrases we are found of sharing with the boys is, "I love you with my whole heart!" (Daddy started it, believe it or not.) They love reiterating this back to us in various forms:
No, I love you with MY whole heart.
And I love you with my ENTIRE heart.
My whole heart is hungry.
Mommy, my heart is hungry for fruit snacks.
Mommy, did you hear me? Let me shout this one out, just to be sure. I SAID MY HEART IS HUNGRY FOR FRUIT SNACKS.
No, my heart is not hungry for a banana.
My heart is sad because you won't give me fruit snacks.
