This Video of Chrissy Teigen's Kids Will Make You Instantly Smile, No Questions Asked

If you have an internet connection, then you're probably well aware that Chrissy Teigen and John Legend's children — 2-year-old Luna and 6-month-old Miles — are some of the sweetest celebrity kids around. In a recent Instagram video, the supermodel and host of Lip Sync Battle took the cuteness level up about a million notches by giving fans a look at Luna attempting to bottle-feed her baby brother. And holy moly, it's one of sweetest sibling moments we've seen in a while. Although Miles seems to be struggling with feeding himself, his big sister is right by his side to offer words of encouragement, coaching him to "use two hands, Miles," and I think my heart just melted.
