Mommy.biz -- Mommy or Mommy Biz
As of February 18, 2016, no live official trademarks were found on USPTO.gov for the exact term
Mommy.biz is a 5-letter (8 letters if .biz is included in the business name) dictionary word: Mommy.
If the business name includes the word Biz, then this becomes a brandable domain: Mommy Biz.
We can see this domain as a popular website for young mothers or a business catering to mothers of small children.
We don't carry too many .biz domains in our inventory, but this extension seems so tantalizing for this keyword.
Indeed, as of February 27, 2016, all the MommyBiz domains have been registered in .com, .net, .org, .info, .biz, and .us (and not by our company).
