The beauty of the unconditional love of a child:
They don't hold grudges (at least not for long).
That look that they give you with their love shining in their eyes that undoes your heart.
That flower (one of those pesky dandelions that invades your lawn in the spring) that they picked or the rock from the driveway for the only one worthy of their treasure-you.
Mommy and daddy kisses must be given before their heads hit the pillow. It's that magic that lets them enter slumber.
Their little legs can't carry them to you fast enough when you've been gone from their side for only a few minutes or a few hours.
You are the one to whom they tell their adventures to.
The only gift that they want from you is your time and attention.
When you are sad or are hurt, they want to kiss it to make it better. If only it was that easy at times.
As I wrote this my two year old was trying to climb into the pack-n-play with the 7 month old saying "I here to break us out". That love extends to siblings (at least until they start to show interest in the same toys).
