Does the word baldfaced exist and if it does can you say a child meaning he is being cheeky?

The word "baldfaced" does exist, but it's not typically used to describe a child being cheeky.

"Baldfaced" usually means:

* Bold and shameless: This is the most common meaning. For example, "He had the baldfaced audacity to lie to my face."

* Without any attempt to disguise or hide: For example, "She gave me a baldfaced lie about where she was."

While it's possible to use "baldfaced" to describe a child's boldness, it's not a common or natural usage.

Here are some more common words and phrases to describe a cheeky child:

* Sassy: This is a popular choice, especially for a slightly sassy, but not necessarily rude, child.

* Impertinent: This word is stronger, suggesting a child who is deliberately disrespectful.

* Bold: This captures the child's confidence and willingness to challenge.

* Mischievous: This describes a child who enjoys playing pranks and getting into trouble.

For example, you could say:

* "He was being quite impertinent, talking back to the teacher like that."

* "She's a bold one, always asking questions that no one else dares to ask."

* "He's a mischievous little rascal, always getting into trouble!"
