Dana is 18 months old now, and her two biggest words are opposites and Rochester (a friend of hers is on vacation in said community).
It’s really funny to watch her say them. It takes all of her mental power to get all the syllables out in the right order and with the correct emphasis.
Kids are great.
On a related note, my pastor’s youngest son has starting saying suffering succotash, but is tragically prone to confusing his s’s with f’s. I leave the ensuing mispronunciation to your agile imagination.
