Chrissy Teigen's Video of Luna Offering to Help Miles on the Playground Is Purely Precious

Luna Stephens should get her big sister badge of honor for the sweet way she treats her brother Miles when they play together. On Wednesday, mom Chrissy Teigen shared a quick clip of 4-year-old Luna and 1-year-old Miles on the playground, and they couldn't be cuter siblings. As Miles tries to climb a small rock wall independently, you can hear Luna offering to help him in the background. His response? He's got it all under control.

"Tell me if you need some boost, okay?" Luna reminds him in the clip. As an older sister myself, I can't even count how many times I must've offered to give my siblings a little "boost" when they needed one. That's the fun of having brothers and sisters, right? Watch Chrissy's video above to see the purely precious moment for yourself.
