My youngest son is three years old and when something is empty, e.g. the ice cream or the breakfast cereals, he basically says: “all gone”.
It is so cute, we love it.
This morning after his first bowl of cereal, he said: “We have no cereal anymore”. I looked up, smiled and realized that he picked that up at nursery school, which he is attending for a week now.
Exposure to different people led to a massive improvement of his speaking skills. It was not a “speaking” school, just other kids of his age, that have parents different than his parents.
I like that.
