Because the two most magical things in the early stages of parenthood are:

* when the baby consciously smiles at you for the first time (they will often smile in their sleep, but that's "only" cute);

* when the baby laughs for the first time - doing something that's funny enough to them for them to vocalize their pleasure can be a challenge!

Both my kids took forever to smile it seemed.

Like you said though they'd smile and even laugh in their sleep all the time... but then when awake all business / serous.
