I agree that's just standard but parent said they speak 4 languages before 2. That's total and complete BS.

I have a 2 year old and I speak with her in one language the mom in another and me and the mom speak in a third language between us.

She knows words in the 3 languages and can construct phrases in 1 or 2 of those languages.

She is is also much more developed verbally than any of the kids her age we meet regularly but she definitely doesn't speak 3 languages.
