Birth

A birth is when a person's or creature's offspring enters into the world, either through exiting the parent from a pregnancy or hatching from an egg.

Mainstream Smurfs Media
In mainstream Smurfs media, since Smurfs do not physically reproduce, a Smurf's birth is usually signified by a stork delivering a baby Smurf from an unknown location to the Smurf Village.

Empath: The Luckiest Smurf stories
In the EMPATH: The Luckiest Smurf story series, Smurfs reproduce physically, resulting in children that are born from the bodies of female Smurfs. In "The Birth Of Psycheliana", Smurfette undergoes the birth of Empath's child Psycheliana. Unlike the births of the children of Empath's fellow Smurfs, Psycheliana's birth was relatively painless for her mother.

Hero: The Guardian Smurf stories
In the HERO: The Guardian Smurf story series, births were usually signified by a stork delivering a baby Smurf from an unknown location to the Smurf Village. However, since Hero's first wife Wonder had been blessed with the gift of being pregnant with his first child Saviour, the births of future Smurfs would eventually come through similar blessings bestowed upon the wives of Hero's fellow Smurfs. The births would be considered painful for the mothers, although Hero would use his Ki abilities to help ease the birthing pains.
