Is it valuable to learn about other cultures in class?

Babies, the movie shown to the class gave us insight to the cultures of the world. 
The movie showed us 4 different babies from around the world, all with different backgrounds. We saw a baby from America, Mongolia, Japan and Africa. The babies were all shown to be treated differently, all with varying degrees of nurturing. The American baby was coddled the most being shown with her parents throughout the entire movie. Meanwhile the other babies were given more independence, from most independent to least, it was the Mongolian baby, the African baby, the Japanese baby, and being the most nurtured was the American baby. The Mongolian baby was left alone a lot of the time with no one around but the animals on their farm. This taught us the varying cultures and how they or if they even do nurture their kids.
Overall, this movie was good for giving us insight into other cultures because it can lead to how we treat our kids.
