Mark Zuckerberg is setting an example of being a responsible parent with his latest photo of 1-month-old daughter Max.
The 31-year-old Facebook CEO posted on the social network on Friday a picture of him taking his baby girl to the pediatrician to get vaccinated. The child looks adorable and cozy in a Patagonia wind and water-resistant quilted and insulated zip-up onesie.
"Doctor's visit—time for vaccines!" he wrote.
Zuckerberg and wife Priscilla Chan, 30, announced their daughter's arrival on Dec. 1. Max is the couple's first child.
