More giggling can be replaced with different synonyms to bring variety into your writing. Instead of using the same phrase again and again, try using some alternatives such as chuckling, cackling, chortling, guffawing, snickering, sniggering or breaking out into laughter. Each of these words has a slightly different meaning, so choose the one that fits the situation you're describing. By mixing up the words you use, you can make your writing more interesting and engaging for the reader. Plus, you'll avoid sounding repetitive or boring. So, next time you want to describe someone laughing, think outside the box and try some new synonyms for more giggling.
