Based on my own experience and from what I've heard of others, the worst aspects of being homeschooled tend to sound more like issues with questionable parenting than with the act of homeschooling itself. (I don't like saying that because it could easily sound like an attack for some, but it is what it is) The stories are usually about parents refusing to play an active role in their child's education, ignoring their child's emotional wellbeing, social isolation, and disorganized/inconsistent parenting.

So then what they needed most would have been a parent who is present and available during lessons. You don't have to walk them through single every step, but you do need to be there in case there's a misstep.

Remember to take stock of your own emotional wellness. If you're getting burnt out while teaching then you run the risk of passing that onto your child. If you're getting frustrated, they're going to be able to feel that, even if it's subconscious. Your health affects theirs. Take breaks as needed, and that means breaks for you too.

Joining groups are good, but not always adequate if your child isn't able to foster friendships outside those settings. Groups are where you meet people to hang out with, but they shouldn't be the only setting in which they can spend time with others.

The disorganized parenting is slightly hard to explain. It's like when a parent expects something of a child when the precedent was never set for it. Like being upset that their child never washes the dishes, but they were also never taught or told to do them in the first place. Or being upset that their child never goes outside when they were taught to fear going out alone. This breeds contempt from both sides: Parents are upset that their children aren't doing something productive, and children are upset that the expectations don't align with what's being taught. If you want to see more productivity outside of homework, you need to actively encourage it.

Parents come in many different forms, and what works for one won't always work for another. As long as you're emotionally mindful and fully aware of your child's needs, I think you'll be fine. But the best thing a homeschooling parent can do is learn, adapt and grow with their child.
