What's your mom work worth?

I have been a SAHM for three years. This is the time I consider my training in the beautiful life period. I wouldn't dream of putting a price to my stay at home years. I read today, though, this article entitled: The price of a mom:$138.095.
Perhaps a little bit more interesting to me is this part of the report stating that:"Moms who have jobs outside the house would earn another $85,939 for their mothering work, beyond what they bring home in existing salary". Well, that would be welcome!
