I think it's a tradition to teach babies how to do the Manseh in Korea. Well, at least that what I get from the Korean community I've been a part of.
What is the Manseh? The action itself requires you to lift both arms, palm open straight up as you shout "Manseh!" The word itself means "ten thousand years", but it can be best translated into meaning "hooray!". Personally, I feel like the meaning goes deeper. To me, it's more of a "Hooray for us, as Koreans for ten thousand years!"
In any case, I'm used to it being part of something you teach babies to do, so they can perform the action in front of other Koreans. It's fun and tradition.
Just last week, Natalie really got it.
This action also really helps to make undressing them easier too. Noah is three, and I still say "Manseh!" to have him raise his arms before I got to take off his shirt. We're working on jjahk jjahk goong (clap clap) and dori dori (shake head) next. Maybe she'll be able to do it at all the Korean holiday parties we'll be attending soon, where all the korean ajummahs will steal my baby and demand she do these things for their enjoyment, but it's ok because I will be enjoying my ham dinner without a baby wiggling in my lap.
~jooliyah, who needs to talk a bit more softly to her baby.
I'm editing to add that I was hesitant to add this post at this time because of fellow Kimchi Mama, Shinyung Oh's recent loss. I think I speak for everyone when I say that we were saddened by the news and am very thankful for your strong and unique voice in our community. As I write about my babies, I am thinking of you, and praying for strength for you....
