Does anybody know if it's been stated whether the free content WotC put out over the past few months will always be free?  I haven't looked at the content yet, but I also don't want to miss out.  I see there's some kids stuff on there I might have to check out for my youngins.

No, it won't always be free. Some already have been removed, with the exception of the drawings and zoom backgrounds.

I also think that they no longer are doing anymore free at home content. 

The unearthed arcana (UA) is only free during its playtest period (about a year). After that it is either archived or published in a book that you need to pay for. You are welcome to re-create it as private homebrew if you want though.

For non UA free content, if you can be more specific, I can probably tell you more about it.

 Last week they went to three days a week, and nothing this week so far - I wonder if that was it? Definitely get it asap.

Frankly it's been amazing to get some of those backgrounds, and the Wild Sheep Chase module from last week is a personal fave :)

I knew I shoulda grabbed it when I first learned about it, but c'est la vie. Will get what I can now.  Thanks for your timely and informative responses!

It was nice while it lasted. Nice benefit after years of paying into D&D.

Most of it is still available if you go to the free material archive.

Yeah, I tapped into archives hoping it was still there and I found a dozen or so adventures/backgrounds and the like.  Should nab some coloring pages for the kids.
