Over the weekend Teigen took to Snapchat to document a little family time and then shared the videos to Instagram on Monday for the world to enjoy baby Luna's adorable laugh beyond Snapchat's 24-hour time limit.
The first video shows Luna's aunt tickling her niece's tummy with her nose, to the baby's delight. The video—captioned, "❤️s auntie!"—offers a hefty dose of baby giggles. Watch the video with the sound on for the full effect:
In another video, captioned "cousie time," baby Luna sits on her older cousin's lap as they both get cradled by an adult. Luna seems perfectly comfortable in her seat and looks over to the camera with a huge smile. Clearly, she's inherited some of her mom's modeling genes!
Chrissy has been documenting a whole lot of family time—including red wagon rides for adults and kids alike and baby-canine bonding time—over the last few days and we cannot get enough.
