Seeing your baby for the first time through an ultrasound is probably one of the most exciting moments for a mother during pregnancy. But what about mothers who are blind?

In an emotional video, created by diaper company Huggies Brazil, expectant mother Tatiana Guerra, who lost her sight at age 17, gets to "see" her baby for the first time thanks to 3D printing technology.

The video is based on a true story, according to the company.

In the video, the 30-year-old from Brazil visits her doctor for an ultrasound. She asks him about the appearance of her son and smiles while her doctor describes her baby.

She tells him that she imagines her baby will have a nose "like a little potato" and a small mouth. She also admits that she "can't wait to smell him".

Her doctor returns 15 minutes later and asks: "If you could touch him, would that let you know what he's like?"

He then presents Ms Guerra with a 3D-printed image wrapped in a white cloth.

The mother-to-be runs her fingers over the small print out, laughing and crying as she reads the braille above the image: "I am your son".

"I am very happy to meet Murilo… before he is born," she says.

The touching moment was recorded as part of Huggies' latest campaign which uses the tagline "Every mom deserves to embrace each moment".

The film, titled Huggies Presents: Meeting Murilo, is the first of several similar ads showing other blind pregnant women meeting their babies through a 3D-printed image.
