gettingtrimmer I've just read a bit of that first thread - yikes!
It's a massive no-no for me, telling me I'm too invested in my children. How can I be "too" invested?? They're my CHILDREN! I gave up my career to be a SAHM (DH's job very incompatible with childcare/other work), we've spent a great deal of money on them, as has the State, and they are going to be citizens and taxpayers and voters and parents and leaders themselves. It would be a shit parent that wasn't invested in their kids.
We just all do it in different ways 
DH really upset me a few weeks ago saying that I micro-manage our children. He meant that I do stuff like remind DS2 to clean his teeth at night (he is 14, has braces, loves sweets, and is incredibly idle) - why on earth would I just let him go for weeks without brushing and end up with decay? Or checking that DS1 has replied to all the emails from his new Sixth form - if he doesn't they will assume he doesn't want the place so of course I'm going to try and be on top of that.
My close friend has a dreadful relationship with her lovely 16yo boy. She never pushes him to do anything, but then moans at him when he sits around and doesn't do any chores. He has not taken up loads of the opportunities offered at school because he's a bit laidback and no one has encouraged him. He now admits to his gf that he regrets not doing those things and wishes someone had pushed him more. It makes him cry a lot
His mum is always on his back, but for really trivial stuff, she never ever tries to help him with his onward journey through school and says "it's his life, he'll manage", which breaks my heart as I can see him leaving Home and not wanting to return. It's such a tough world, why wouldn't a parent do everything they could to help their child achieve their potential? Whether that's by helping with essays, reading books, paying for tutors, driving to sports clubs, nagging school for SEND help, researching revision aids, cooking a nice breakfast on exam days, organising a good study area, praising their efforts, listening to their future plans, taking them seriously, etc etc. She thinks I am overly invested in my kids but I don't care and just try to let her son (who is also friends with my son) know subtly that there are other adults he can talk to if he needs to. Her background is very different from mine and I think she has a bit of a chip on her shoulder about money and status. Her DS wants to go to uni and while she says she's proud, it can feel like she's deliberately sabotaging it because she subconsciously thinks it will turn him into a snoooty type who won't then want to know his family.
Sorry, this was a bit ranty
Can you tell I'm home alone with lots to do but in need of distraction!!
