Many vaccines aren't vegan-friendly (they're often grown in eggs), and pretty much all of them go through animal testing stages during clinic trials. It's not at all surprising that vegans would be anti-vax.
From discussions with vegans I've known, the objection to eggs and dairy is largely based on the (mis) treatment of the animals as part of industrial scale production. It's not (usually) a mystical belief about the sanctity of some life essence - more about observable apparent suffering.
Unless carefully managed, a vegan diet has a chance of lacking some critical nutrients for the development of young children. I think a vitamin B12 deficiency is common.
Meat/fish and byproducts are generally considered a "quick fix" for a great many dietary issues. Giving a baby something with meat in it once a week when they start feeding, once a month after 2 years (or more often) will fix most diets. Any real vegan diet will need to consider a great many factors.
Even vegan diets that aren't going to kill you in the long term are still going to cause problems. For example, a vegan diet with >60% fruit (or fruit and grains), will cause amino acid shortages. Too little fruit, of course, causes Vitamin C shortages.
Luckily it's easy to fool yourself into eating meat. Many forms of candy, for example, are meat byproducts. So is, of course, a latte.
How is milk from a breast of a human vegan?
Is there a definition of veganism that says an animal product that was given with consent is considered vegan?
B12 supplementation is recommended for a vegan diet at any age. Besides that, I'm not sure what you mean by careful management. Eating a normal varied diet where the proteins come from plant sources gets you covered.
Yet on the page strictly about babies and children, the recommendation is to "[use] a moderate amount of poultry meat and some red meat as a source of protein. [...] Eating fish two to three times a week is recommended for the whole family."
There's far too many stories of babies dying of malnutrition on vegan diets. While it's possible to make them healthier for them, let's not go saying it's recommended, just like children can survive on crappy junk food (and plenty of them sadly have to), provided it's fortified with nutrients for them. There's a difference between surviving and thriving.
That very same link states that "a carefully composed vegan diet" can be beneficial. Thats my point -- with a vegan diet you have to be much more conscientious about nutrition. Many people are not. With your average healthy omnivorous diet, you rarely have any significant nutrient deficiencies that you have to worry about. Said diet ends up being simpler to implement in practice. That's what I mean by careful management; A healthy vegan diet for children is not impossible, but it takes more effort.
My ex had the same issue while on a vegan diet - and she was an adult. Random dizzy spells and faintness to the point of almost passing out.
It boggles my mind anyone would ascribe to a diet that literally requires vitamin supplements through artificial means in order to be complete. And those are just the obvious deficiencies.
Vitamin B12 is made by bacteria, it's in all dirt, and untreated water. You absorb it through your skin. It's pretty easy to see how it wasn't long ago that we would be having an abundance of vitamin b12 from everywhere.
Cows don't make it, they eat it in soil. Which, actually, because most of them are factory farmed, they are fed the supplement. Nothing natural about that; in fact, you're just skipping the middle-man and cruetly.
"But I only eat grass-grazed happy cows!" Good for you! Now how about a solution that can work for everyone.
You want to know what the real next pandemic is. It's going to come from the unbelievable abuse of antibiotics the meat industry is responsible for. Medicine will be set back a century.

I used to think that, but at some point I thought: what's the big deal? If you're still eating healthy, still eating tasty food, and you just also consume a pill or two every day, is that really so bad, or does it just feel "wrong"?

Most non vegans also get their B12 through supplementation. It just is fed to animals directly or indirectly as cobalt supplement.
> Most forages and feedstuffs fed to dairy and beef animals do not contain adequate quantities of cobalt to support the rumen and animal requirements. Consequently, supplemental cobalt must be added to beef and dairy rations. [1]
