I had 6 weeks as that was what my employer allowed. I didn't take it all at once, 4 weeks and 2 weeks later. I found that she needed help more during teething and sleep regression so it might be good to split it up if you can, also helps you keep on top of work.
But would say it's important to ask what she feels she needs. I wouldn't worry about your employer. Also, with the lack of sleep during those first few weeks, I can't imagine anyone is productive at work.
I would say that so long as communities are governing their own tags but it's somehow monitored to make sure two tags don't mean the same thing it could be a real positive, especially for support topics etc.
Transhuman I expect. Technological body modification. I think it's probably more commercially viable that biological so will come first.
