Many of our identities are with us from day one, but no one is born a parent. A parent is someone you become so, theoretically, we should all be able to remember the person we were before having kids, to empathize and see things from that perspective.

But whether its a result of exhaustion, overwhelm or the way our brains and identities change so dramatically upon becoming parents, it seems that in many cases, parents do not, in fact, remember what it was like before they had children, and they often end up doing things that drive non-parents up the wall.

Take baby talk, for example, which has been observed in many different cultures . The way caregivers modulate their tone, cadence and vocabulary when speaking to their children may not sound so cute to other adults in the vicinity.

In a recent survey of 977 people who were asked their opinions about baby talk, 69% reported that they found it annoying when parents use baby talk to speak to their children. An almost equal number of future parents (68%) said they did not plan to use baby talk with their kids.

The survey, conducted by Preply, a company that matches people with language tutors, found that these were the most frequently used baby talk words:

1. Night-night
2. Tummy
3. Binkie
4. Blankie
5. Boo boo
6. Poo poo
7. Oopsie
8. Baba
9. Owie
10. Ouchie

The characteristics of baby talk that respondents found most annoying were speaking at a higher pitch (75%), exaggerating facial expressions (53%) and singing their speech (51%).

Slipping into baby talk isnt the only annoying thing that parents do. A different survey of 977 people conducted by the same company found that a majority of non-parents (70%) said they find it annoying when parents continually bring the conversation back to their kids. A similar majority (72%) dont want to hear any details about your kids bodily functions.

There are also a number of phrases parents use that non-parents find annoying, the top offender being, Youre not a parent, so you wouldnt understand, which 68% identified as a sentence they dont want to hear, followed by, You think youre tired now, just wait until you have kids! (51%).

The surveys results suggest that parents arent the best recruiters for the job. Sixty-two percent of people who plan to have kids said that they are less interested in doing so after talking to a person who is a parent, and 39% said they do not typically enjoy conversations with parents.

We asked folks on the HuffPost Life Facebook page to identify the parent behaviors that bother them most. Some commenters wondered if the question would only lead to more division between parents and non-parents, but we think theres value in parents hearing the perspective of people who dont have kids, and vice versa.

Here are some of the most annoying things that parents do, in the words of HuffPost readers:

Letting their children play handheld video games with the volume on in public places. Either mute it or give the kid headphones. Alicia Griffiths, New York City

Expecting childless people to work holidays or sacrifice planned time off because we dont have kids so somehow our time is less valuable or our plans are less important. Kyndall Osterman, Ohio

Not keeping their kids from running, and running into people in stores and other public places. Mara Viviano
