I have a 23-month old granddaughter who lives around the corner from me. Her mom lived with me when she was that age. Strictly speaking, they both began with crying, grunting, babbling, vocalizing, and such. And that's just considering verbal language. I'm pretty sure that I was much the same way.
All of us were surrounded by English-speaking people and eventually transitioned (or are currently developing) into this common household language. As such, English is best argued as my second language.
If you hadn't asked so pointedly, I might not have thought of it that way. Thanks, that was fun. I'll have to take that into my next encounter with my reigning favorite toddler.
How about you?
Why did you ask?
Are your questions better than my answers? If so, better at what?
