My brother recently got his first child. In Finland it's customary to celebrate a new baby in "varpajaiset" which loosely translates to "counting toes event". It's a bit like baby shower, but with the male relatives and friends and a lot more drinks.
The etymology is actually misleading. Originally it has nothing to do with toes or feet, just a bit lost in translation. Originally it's a loan word which meaning had already lost in the original language and turned to relating to feet which in turn turned to toes in Finnish.
The real origin is lost in history. The only think that is certain is that it used to mean something related to foot. Probably from the custom of bringing food and other supplies to the family of the newborn.
There is actually another custom in Finland that is more related to the food and supplies part called "rotinat". At least in eastern parts of Finland. That originated more from the russian side of the culture.
Anyway, today we are celebrating the newborn with my brother.
