act one's age

Idioms & Phrases

act one's age

Behave more maturely. Although the phrase often is used in asking children to act in a more grown-up fashion (Only babies suck their thumbs; act your age), it also may refer to an adult who is, sometimes deliberately, acting much younger than might be considered appropriate (Grandpa, it's time you stopped climbing ladders and acted your age).
