To laugh -vs- to smile.
Is "to laugh" typically reflexive because you, yourself, are laughing?
La niña se ríe.
Los niños de la fiesta de cumpleaños se ríen.
And does "to smile" typically take an indirect object because you are smiling at someone?
Ella le sonríe a su esposo.
La doctora le sonríe a la niña.

I wouldn't make the mistake of comparing the uses of sonreír(se) with reír(se).
When you are smiling at someone sonreír is still an intransitive verb. The someone is not the d.o. of the verb smile. You smile to someone. That is why the i.o.p. is used.
La doctora le sonríe a la niña.
(if a la nina was the personal "a" + d.o. it would simply be: la doctora sonríe a la niña.)
Ella le sonríe a su esposa. (intransitive sentence)
reír(se), however, can be intransitive or transitive.
Le reí el chiste. (I laughed at your joke...transitive) [the le showing possession or who is effected by the verbs action ...replacing the possessive adjective in the English sentence)
Me reí cuando usted contó el chiste. (I laughed when you told the joke...intransitive) (reflexive...I laughed to myself or intransitive)
All of the pictures in Tosh's reply are intransitive uses of the verbs.
I don't think there is much difference between sonreír and sonreírse. In Mexico, it is common to use the pronomial form but both are definitely used. In the progressive tenses, it may be more common to omit the reflexive pronoun - Don't you agree that "Estaba sonriendo" sounds more normal than "Me estaba sonriendo"?
BUT: when you combine sonreírse with an indirect object, the construction with sonreír and sonreírse is different.
Le sonreío a ella, he smiled at her.
Se sonreío con ella, he smiled at her.

Here are the examples I was talking about.
If it was "sonrierse", why are they using "le"? Estoy confundido! :(

As long as the smile is directed at someone, then yes.
Here's another goodie
Reírse
Would "me sonrío" be "I smile to myself?"
