I'll have had 2 terms pre mat leave, with just 1 to go, as I'm not in Aus. And I don't have a good relationship with one of them! Saying that, they're better for me than for some other teachers, but I still don't trust they'd behave for a teacher who's leaving.

Most of my students will be happy for me and interested. I just don't want them fussing about me I guess.

But does the fact it isn't the start of the year change anything? Or should I say now as I've had the NT scan and everything's going well?
Oh sorry, I made an assumption you were in Aus.

Hmm. If they've had you for nearly a while school year you might still need to give them a bit of preparation,even if it's only so they treat the next teacher okay

You could not actually tell them.... But start wearing one of those tshirts announcing your pregnancy and wait to see which students actually ask, and how long it takes to get around the school. Lol. Could be funny

It really is your own business, and if you don't want to tell them why you're going on leave you certainly don't have to. But as a parent I'd probably want to know that you're at least going on leave, just so I could ask questions etc before you go if I need or want to,
