There’s nothing that warms the heart quite like babies with big smiles.

Which is perhaps why a video posted by the National Down Syndrome Adoption Network earlier this month has quickly achieved viral fame.

The clip, featuring an adopted baby with Down syndrome grinning happily at her adoptive mother, has already been seen by more than 14 million people.

It’s not too difficult to see why: the baby is absolutely adorable. She knows she’s in a loving family, and the joy she’s spreading is simply an extension of her own contentment.

The National Down Syndrome Adoption Network (NDSAN) was established in a bid to ensure every child born with Down syndrome has the chance to grow up in a loving family.

The organization was founded by Robin and David Steele in 1982 after they fell in love with Martha, a young girl with Down syndrome residing at a children’s home.

Well that clip certainly brought a big smile to my face! How about you?
