It's official: 2015 was the year of the baby debut on Instagram. Stars from all walks of life took to the social media platform over the past 12 months to share photos of their newborns, and we were thrilled to have our feeds filled with their adorable offspring. While some babies made an appearance within days of their birth (like Justin Timberlake and Jessica Biel's first child, Silas), others took months to give us a glimpse of their sweet faces (like Kourtney Kardashian and Scott Disick's little guy, Reign).

Any way you look at it, the platform has become the place for celebrities to show off their little bundles of joy. Check out 22 babies with famous parents who made their debut to the world through a ’gram in 2015.
