I don't think it does anything crazy to babies necessarily but I also don't think it tells you anything really practical, other than telling you how you react to that particular drink on a particular day.
I passed my test with DS, with DD I failed it. They were going to give me the 3 hour one but I said screw it - if I failed that one too I would be labeled high risk etc. So I chose to do the blood testing at home for a week and I never even came close to having an issue. This time around I did the same thing - skipped the drink foreplay altogether and just tested for a week. Insurance covered the blood sugar meter. And it was based on real life results based around what I eat and drink etc. Much more realistic for me.
I think it's awful that you're made to feel anxiety over "passing" or "failing" a test. It's like school or something. It's one thing to be aware of what's going on in your body, and if you have an issue it's good to know about it so you can correct or help it or whatever. (Had they not tested me for thyroid issues I never would have known my levels were way off and needed medicating!) Considering my own father had diabetes, that puts me at risk for it, and I know I felt better knowing that my blood sugars were healthy. BUT I just don't like the whole way this particular condition is tested for and how some OB's make you feel like you're a rebel or something for wanting to do the blood meter thing instead.
