Define fussy eater. Because IMO what some people consider fussy others just consider to be different tastes.
So e.g.if your fifteen year old refuses to eat anything but chicken nuggets and chips or toast and peanut butter then I would say that is fussy and I wouldn’t stand for it.
But if e.g. he just doesn’t like certain things which you do then I would likely accommodate. E.g. my DS who is now seventeen doesn’t like spicy things. I didn’t either at his age really. Spice is IMO an acquired tast and not everyone has it.
On the other hand he will eat most other foods so I just don’t cook things like curries when it’s just the two of us and wait until he’s out to maybe make a curry for me and my DP when he’s here. Last night for dinner we had sea bass with prawn risotto. By those standards I definitely don’t consider my DS to be a fussy eater. IYSWIM.
Lifts depend very much on where you live and the availability of e.g. public transport, and often the cost of it. We live in the London area so public transport isn’t an issue, plus I don’t drive so there is no choice but for DS to find his own way to school/activities. But e.g. my sister drives her kids to their activities although they catch the school bus to school so there is a middle ground.
It never ceases to amaze me when people seem to think that any child over the age of about eight should just be able to “cook himself something,” while that’s true in part, I also don’t necessarily think it’s wrong to ask if his mum could make him something to eat, but then everything is in the attitude.
My DS would ask, but he is also a perfectly good cook and would make something for himself, and even for me if necessary. But if he came home demanding then he would be told to cut the attitude.
And yes, I would be pissed off if an ex failed to provide dinner for his child while he was there...
