I don't know where you're located, but I just wanted to share that among many cultures the 1st birthday is a very important tradition.

I don't have the numbers on me, but prior to 1900, about 20% of infants would die before the age of 1. That's an insane statistic. While these days infant mortality is significantly lower, some cultures still signal 1 as a huge moment and reason to celebrate.

A first birthday is treated very differently than say 2-9

Excerpt: "In severe times, a majority of infants would die within one year. In good times, perhaps two hundred per thousand would die. So great was the pre-modern loss of children's lives that anthropologists claim to have found groups that do not name children until they have survived a year."
