In New York, you can see anything on the subway.
Riding back to New Jersey on friday, the train door opened and in came two parents with a toddler about Jack's age in a stroller. They bent down and chatted with him playfully. As I heard the boy respond, I realized the little guy had a French accent. I then immediately noticed that his parents were speaking sing-songy French to him. All of the young boy's words and sounds were the same cadence as Jack's, but En Francais. I couldn't understand anything they were saying, though I suspected it was the same kind of conversations we have with Jack now. But, then he pulled out a "Thomas the Tank Engine" toy and showed it to his mom and said "Mama, Choo-Choo!" She said "Oui, Oui, le Choo Choo!"
Some things are the same in any language. I smiled all the way home, missing my little boy.
