It probably does; you really should work on that. (I say that as a fellow introvert.) Eye contact is one of those things where moderation is definitely key; too little and people think you're shifty or withdrawn, too much and they think you're a psychopath or something. A good amount shows confidence, but too much is intimidating. The way you act is going to severely limit your ability to socialize and get good employment, a girlfriend, etc.

As for animals and babies, that makes perfect sense too: those things aren't usually a threat to you in any way, either physically or socially, except maybe for large and aggressive dogs in which case strong eye contact is useful because it shows the dog that you're the "alpha dog".
