This Is When Babies Start Smiling on Purpose While Feeling Pure, Innocent Happiness

Having a baby can be pretty stressful. There's little sleep, little time to yourself, and very little time for romance. When my son was a baby, I once fell asleep while brushing my teeth! As a parent, we want some sort of reward for all of that hard work. While the hugs, kisses, and "I love yous" are a year or two away, you will be pleased to discover that a genuine smile is lurking right around the bend.

I snapped countless photos of my son when he was a few weeks old, and bragged to people that he was already smiling. When I told his pediatrician about his talent, she informed me it was a reflex, and that all infants smile when they pass gas.
