Vegetarian is not vegan. Many vegetarian consume dairy products and sometimes seafood.
Nobody is talking about vegetarians, why is everyone telling us about their vegetarianism.
The vegan diet is part of vegetarianism however. Many people use vegetarian for the ovo-lacto-vegetarian variety, but vegetarianism is an umbrella term that includes multiple diets with plant based foods as the basis. There are many who would even argue that
veganism is the true vegetarianism. Strict or total vegetarianism is dietary wise exactly the same as a vegan diet, it's only that veganism stands for way more than diet alone, it's an ethical way of life.
Pescetarianism however isn't part of the vegetarian dietary umbrella, since it involves the eating of animals in this case fish. (No major vegetarian association accepts the claim that pescetarians are part of the vegetarian 'family')
I'm a vegan and I'd never raise my kid vegan.
Why not? I don't understand how a person can be vegan and not raise their kid vegan. Are you going to learn them to speak another language than your own, at first too? If certain values and principles are important to a person, isn't it normal to share them with your loved ones. When a kid grows up they can always decide on their own, what they'd like. I'm pretty sure though that a lot of kids oppose the idea of eating animals, it's why a lot of people sugarcoat what actually happens to them, or have to create elaborate justifications for them.

As for the concern about your baby's health, which of course is understandable, I'm pretty confident that for every malnourished vegan baby, there are dozens if not hundreds that are raised healthy. The issue here is not veganism itself, but the fact that the medical world is still not well versed in the nutritional scope and spectrum of veganism. These parents clearly didn't know what they were doing, and apparently there also wasn't the required medical/nutritional advice to correct it. As someone already quoted, well-planned vegetarian and vegan diets are suitable for all stages of life.
