And her question WAS answered. The court may not allow her half of daycare expenses if any, due to the fact that no one knows if she's paying grandma and grandma is hiding her income from the IRS. If I were dad, I certainly would object to paying "grandma-nanny."
Its a bit presumptious to assume that grandma is going to hide her income, she may, she may not. Lots of people who get paid for private babysitting don't hide their income, they are smart enough to know that they need the social security credits.
Grandma is quitting her job to do this...I suspect that grandma wouldn't do that for free...and probably couldn't afford to do it for free.
The bottom line is that lots of relatives get paid for providing daycare...and lots of ncps are ordered to pay a portion of those costs. Some of the ncps get cheated in the process, and many others don't.
I used private daycare when my daughter was an infant (I had a nanny who was a long time family friend) because I would never have sent her to a daycare either. Therefore I have sympathy with others who want the same.
I also have some sympathy for posters who get snippy. Anything to do with kids and separated parents is a very emotionally charged situation for most people. Its not so strange that they react badly when they hear something that is totally different than what they expect to hear. The smart ones realize that they behaved badly and try to change their attitude. The not so smart ones keep up the "tude".
