And from first steps to the first day of school, every new milestone is documented - including some embarrassing ones.
But parents might want to think twice about what they share online after it emerged that a teenager is suing her parents for invasion of privacy.
Why? Because they posted pictures of her when she was a baby that include having her nappy changed and sitting on a potty.
The 18-year-old woman, who lives in the Austrian state of Carinthia, claims that since 2009 her parents have made her life a misery by constantly posting new pictures of her on their social media accounts from when she was an infant.
She said the pictures allegedly included embarrassing and intimate images from her childhood and added that they were shared with her parents' 700 online friends.
Michael Rami, the woman's lawyer, says that to date her parents have posted 500 images of her on social media sites without her consent. He believes she has a good chance of winning the court battle.
The teenager said: "They knew no shame and no limit - and did not care whether it was a picture of me sitting on the toilet or lying naked in my cot - every stage was photographed and then made public."
She told local media that despite her requests, her parents have refused to delete the photos, which prompted her to sue them.
She said: "I'm tired of not being taken seriously by my parents."
Her father believes that since he took the photos he has the right to publish the images.
Yet Rami said that if it can be proven that the images have violated her rights to a personal life, her parents will lose the case.
And it might also mean the parents have to pay money to the child.
