Depends, really, doesn't it? For some students, they will be needing things like kitchen items or whatever for the first time, and if there aren't any spare ones at home then they're going to need to buy them. Or if they have a double bed at home and will be a single bed at uni, they're going to need some single bedlinen. Yeah, they could buy that on their own. But it doesn't seem like excessive or mollycoddling to me for parents to have a day out shopping for that sort of stuff with their 18-year-old. It just seems like a nice thing to do.
Similarly, there's 'care packages' as in something the parent gives the kid as a nice little 'Good luck! Here's a little gift of some stuff you might find useful', and there's 'care packages' as in something they genuinely seem to think their child will not be able to source without help. The former seems normal (although clearly not essential, just a nice gesture) to me. But the latter seems infantilising.
Again, making the bed up - if you're helping your kid carry boxes of stuff into their room, and they're busy putting their clothes in the wardrobe or introducing themselves to the person who's moving into the room next door, then it seems perfectly reasonable to think 'Oh, I'll just do the bed while she's busy, it'll save her the bother later' just to be helpful. But if people are making up beds because they think their kid won't be capable of doing it themselves, that's ridiculous!
The dentist and optician thing I do not get at all though. If they need to see a dentist they can just go to the dentist, ffs, they don't need a parent for that! Or a food shop. I mean, they can buy a bag of pasta unaided, surely?!
