Life
Sometimes babies have an immediately negative reaction to someone, usually noticeable by their overwhelming screams and wails. Their judgment, however, can be somewhat difficult to decipher, especially if their inexplicable hatred is directed towards someone you love or admire. Don't worry, though; more often than not there's no real rhyme or reason to your baby's logic. Sometimes the people your baby is bound to hate has nothing to do with the people in question, and everything to do with your baby being, well, a baby.
Over the course of my childcare career, I cared for over 25 babies and small children. It's safe to say that I'm proud that I could always elicit a smile, and comfort them when they cried. OK, not always. There was one child in all that time, a 9-month-old baby, who decided he just didn't like me. He would cry when I approached and push me away, preferring to whimper alone than be held by me at all. I persevered, thinking we could build a relationship with some time, but that instant dislike also happened to be permanent. I had to reluctantly tell his mother that I was not her sweet son's favorite, and that I thought it would be best if she looked for a different caregiver. A few weeks later I bumped into her in the grocery store and was pleased to hear he had settled in with his new daycare provider and, as a result, was much happier.
So believe me when I say that sometimes your baby just isn't going to like someone, for reasons unknown and without it really being anyone's fault. Now, as a mother, I can attest to the following people who may or may not become the subject of your baby's hate. Hey, babies gotta baby.
Their Daycare Teacher
If your child can't settle into a new daycare, despite allowing a suitable transition period, it might be due to a personality clash with their daycare provider.
Before switching classes or centers, however, I think it's important to remember children can be fickle and change their mind swiftly. For example, my toddler proclaimed to anyone who would listen that he hated his teacher. Now, just a few months later, he can't stop singing her praises.
The Baby You Want Them To Be Friends With
My friend had a baby just a few months before I did, so we spent a significant amount of time fantasizing (usually when we were pregnant) about our children growing up to be the best of friends. We even arranged baby playdates, expecting to cultivate some sort of friendship. The only problem? They hated each other.
It just wasn't meant to be. When we tried (again) when they were toddlers, they remained sworn enemies, despite our best intentions.
Random People For Random Reasons
Babies can be random AF, so random reactions to totally random people is par for the baby course. For instance, a little girl I cared for had a prejudice against men with facial hair. She wailed with reckless abandon whenever my mustache-faced husband entered the room (and apparently had a similar reaction to her grandfather, who had a beard).
Unfortunately there is no way to control the way babies react to other people, what with them being independent mini-people and all. However, you can change your reaction to their response, and encourage anyone they have a negative reaction towards to remember it's not personal.
