Have a blog per user?

Hi,

I run a childcare centre. Each day, we need to take photos and write some notes on each child to show their parents. We currently do this paper based.

Is it possible, for each parent to have a login in wordpress, and then for us to blog that information just to that one parent of that particular child? For privacy reasons, we can’t just openly blog the information to all parents. Or maybe, when we are posting a blog, to select only 1 user (parent) that can see that blog?

We have new parents join each week, so it would need to be sustainable.

Thanks in advance!
