Seeing little kids faces when they're out hiking in nature, especially when they get really excited about the animals they're seeing.

The joy on your little niece's face when you laugh as she does something silly because she knows you enjoy her silliness. :)

The excitement for school the next day when you buy new, fancy stationary.

When a baby at the table next to you in a restaurant keeps looking at you and smiling.

Holding your old child for the very first time.

When your niece remembers and uses a word, the proper way, that you taught her in sign language. :)

A big hug and kiss from your one year old niece. :)

The delight in a child's eyes when they've accomplished something for the first time.

Reading a book to a small child.

Playing with someone else's baby and not having to change the diaper. :)

The moment when the overtired fussy baby snuggles close and finds sleep in your arms

A warm, giggly hug and kiss from your infant baby.

The even breathing of your child as they're falling asleep.

Sitting across from a toddler at a restaurant and making faces at him/her that are made right back at you.

When cute children ask whether you will come back to play with them.

Coming home at the end of the day to happy smiles from your kids.

A smile from a baby.
