I look at this like cloning, something that's probably never going to go anywhere. But entertaining the discussion, I'm definitely not against using science and technology to improve life and help people who need it. I'm just saying that I don't think we should mess with genetics 'just because'
You say that as if you think scientists are just doing this for laughs or because it's interesting. The reality is that there is huge potential for such research, as it could lead to the end of birth defects and lead to improved quality of life.

I don't think it's worth the risk of just trying out new stuff to see what happens, or to make sure people get a kid with a certain color of eyes. I think we have a higher error rate than nature itself, and there's a huge risk of screwing up someone's life when you start messing with this stuff.
Again, you attempt to trivialise legitimate research by associating it with cosmetic changes and experimentation. We need a regulatory framework in place to ensure that any genetic changes made are thoroughly understood and of legitimate benefit. Genetic experiments on animals like mice and primates can give us a good understanding of what impact the changes will have, which can be combined with scientific modelling and gene research.

I can't think of any example where having three parents offers an improvement for any of the issues you mentioned.
However, if it poses effectively no risk to the individual then why shouldn't multiple people be able to share a genetic child? Just because it doesn't happen in nature doesn't mean it should be discounted.

And since humans are designed to have two parents, genetically speaking, I can't help but think that bad things could come of trying to change that.
As I have said, thorough research and regulation is necessary to ensure that the risk of adverse effects is minimised or eliminated altogether; and while it is natural to express scepticism about such research, without a learned understanding of genetics your concern is pure speculation.

Still drugs and genetic manipulation on a designer "baby" level is not even remotely the same, again, look up the dangers of lack of genetic diversification.
Given the scientific understanding of the importance of genetic diversification any regulatory body would need to ensure that genetic diversification is maintained and that there isn't a tendency to rely on certain genetic traits. Considering that even laypeople such as yourself understand the risks it is safe to assume that scientists and regulators also do.
