Baby Idioms

We are delighted to announce the arrival of the latest member of the Intrepid English family; our wonderful teacher, Jen, has given birth to a beautiful baby girl and we are pleased to report that mother, baby and family are all doing well. Congratulations, Jen!

In celebration, I’ve polished up one of the most popular Intrepid English blog posts focusing on baby idioms.

In English, we have several idioms related to babies and children. Here are some of the most common baby idioms for you to use in your English conversations.

1. Child’s play

If something is child’s play, it means it’s such a simple and easy task, even a child could do it.

  • If you’re not confident at cooking, I have a really simple recipe for tomato soup. It’s child’s play.
  • The new computer system is child’s play. I learned how to use it in a couple of hours.

2. Sleep like a baby

To sleep like a baby is to sleep really well.

  • People who say that they sleep like a baby have obviously never had children!
  • I slept like a baby for the whole flight from New York to London.

3. Out of the mouths of babes

People used to use this idiom when a child would say something surprisingly intelligent or wise. Nowadays, it is used in a more sarcastic sense, when a child says something brutally honest.

  • Grandma, your hair reminds me of a bird’s nest… Thank you, sweety. Out of the mouth of babes!

4. New kid on the block

In English, we often refer to children as kids. If we describe someone as being the new kid on the block, it means that they are new to the company, team or organisation, and they don’t yet know how everything should work.

  • Lucy is the new kid on the block so please make her feel welcome in the team.
  • It seems like only yesterday when I was a new kid on the block at this company.

5. Smooth as a baby’s bottom

Extremely smooth and soft with no flaws or imperfections.

  • This fabric is so silky, it’s as smooth as a baby’s bottom!
  • The white sand on my favourite beach is as smooth as a baby’s bottom. 

Exercise: Now it’s your turn. Fill in the gaps in the sentences below with one of the baby idioms above.

  1. I love the texture of peaches. They feel as ____________________ .
  2. Sam learned to play the guitar in less than a year. He said it was ____________________ .
  3. Luke is training a new starter at work. It can be hard to be the ____________________ .
  4. I’m absolutely exhausted. I’m going to ____________________ tonight!

Interview with Alyssa Ordu

Hello, and welcome to the Intrepid English podcast. My name is Lorraine, and today, I have a conversation for you. My friend Alyssa is a Diversity and Inclusion Consultant in London. And when I told Alyssa that we were creating a diversity and inclusion course, in the intrepid English Academy, we had a lovely conversation about why diversity and inclusion are so important. I asked her to join me on this podcast as an expert in this field, to break down these big topics so that our English learners and the listeners of this podcast can understand a little bit about what diversity and inclusion are, why they’re so important, and give you a little bit of language that you can use to increase your awareness and broaden your horizons in these essential areas.
