Kim Kardashian and Saint West Have Fun With Snapchat Filters on His 9-Month Birthday

Dynamic duo can't get enough of pretending to be deer

Happy 9-month birthday, Saint West!

Kim Kardashian's son hit a milestone on Labor Day and the mom-of-two is celebrating by giving her fans a sweet treat: adorable pictures and videos of her tiny tot on Snapchat! A lover of filters, Kim first used the old man look on her anything-but-old baby, and it couldn't be cuter. If his adorable laugh and squealing weren't enough of an indicator, it's clear that this is one happy baby boy. She then used the deer filter on her son, transforming him into a little Bambi look-alike. The Keeping Up With the Kardashians star then got in the on fun, taking selfies with her son while also wearing the deer filter.

We can't believe Saint is already 9 months old! But just like his sister, Saint is quickly becoming acclimated to the social media app. When Kim first introduced daughter North West to the picture-sharing platform, she said she was scared of it and didn't want to have anything to do with what she called "Snapchap." Now, North often finds herself the star of Kim's account, interchanging funny and flattering filters. At just 3 years old, North has already figured out how to become a social media star!

Other than a few videos, Kim has kept Saint out of the public eye. But whenever she does share some of her moments with him, they're enough to turn any frown upside down. The last time she shared a peek of her son it was in the form of a quick Instagram video of him nonstop giggling. His laughter proved to be infectious, and since then we've been counting down until his next social media appearance. But Kim has said she's intentionally keeping his public appearances to a minimum.

"So truly, I was not posting about my son because I wanted him to be able to go to the park every single day like a normal human being and nobody knows who he is," Kim admitted at the BlogHer 16 conference in Los Angeles. "He's 8-months-old now, and people thought he didn't exist. People thought I had a whole fake baby and I made this whole thing up because I wasn't posting about it. And to me, that's so ridiculous."
