Some of our favorite starlets are celebrating Mother’s Day as moms for the first time this year!

We got so many new babies to “ooh” and “aah” over this year, thanks to all the celebs who made the leap into motherhood! We love when Kendra Wilkinson shares photos of Hank Baskett IV on Twitter, and when Kim Kardashian tweets about how much she loves being an aunt to Kourtney‘s new baby, Mason Dash Disick. And we’re STILL not over Sandra Bullock‘ surprise announcement that she adopted baby Louis Bardo Bullock in New Orleans and managed to hide him for months! Hollywood got tons of great new moms this year, and we’re celebrating them on their big day!
