Argh I should be going to bed but this is so interesting...

When you talk about expectations, do you mean your wants for them, or what you see of them & what direction you think they might take?

We have no expectations (in the sense of wanting) for our kids - other than, I will be overjoyed if they manage to have somewhat happy, fulfilled lives. DH has told DS1 that if he wants to be a garbo, or a doctor, or a lawnmower guy, or a footy player....it's all the same to us - as long as he is happy.
Don't care if they are gay or straight, get married or not, have children or don't (although I do have a secret longing for grandkids & if I don't get any of my own I will have to beg, borrow or steal some as per Lady Zaidie ).
Anything goes if they are happy...it's will be enough for me if we produce happy, semi-well-adjusted adults I don't care about the rest.

Expectations based on what we see...well, yes.
I don't expect them to hold, you know, I also expect that they might change as they grow, and I realise they change & develop, but IMO one of the most fascinating things is to see their individual personalities growing & developing & I love to imagine what they might be like when they are older.
For example DD1 is quite creative & ATM enjoying photography, she loves fashion but in a very creative way, music, design etc. We have often said we wouldn't be surprised if she ends up doing something with a creative/ design bent. I can see her spreading her wings a bit too & travelling.
The kids do it too...DD1 often wonders what her brothers will look like & be like when they grow up.
But this is all based on what we see rather than what we want ITMS...because I don't want anything for them other than happiness.
It's been hard enough for me to be happy in my life.. if they can do it that'll be enough for me
