I look at babies that are not mine sometimes several times a day and so it is odd to hear someone express hatred for one. Although a quick google of "hate babies" shows that there are apparently a lof of people who use this strong emotion to describe what they feel when they see or hear an infant.
It appears most of those people are NOT parents. I would argue this is a good thing -- while I do not find research evidence that child abuse is higher among self-described baby haters than plain old parents, there is plenty of anecdotal evidence on this.
Rather than use the word "hate," I'd challenge those who lean toward this work when describing how they feel in the presence of small humans who have not yet learned to regulate their body systems and communicate with words to go a little deeper and see what's under the feeling. Fear, misunderstanding, lack of information, low-tolerance for high-pitched sounds and frequencies, the need to be in control....all of these might be at the heart of the experience and all can be addressed so that you do not send that energy out to little people who really don't deserve the venom or parents struggling to raise a baby (it's hard work).
Even as someone who works with brand-spanking new babies daily, I am hit regularly with myriad feelings: I am sometimes overwhelmed by the needs of a baby, I am sometimes frustrated, I am sometimes intimidated, I sometimes feel inadequate. These are normal feelings. Pure, across-the-board hatred for babies is not normal. Or healthy.
