I am doing some research on the types of digital identities created by parents for their children, through the content that they share on Social Media.

Are you aware of any study (academic or otherwise) offering some sort of classification of the content posted by parents on social media? I.e., not about the motivations, or consequences, or even the frequency, but about what is actually shared - both type (e.g., photos vs status updates) and content (e.g., funny photo of child, status update about milestone).

Thank you
