He can say a lot of words, and some short sentences (e.g. "Daddy, good morning."; "Mommy, sing ABC."; "Let's go."). I think he fully understand what we are talking about at all times. He can say the names of many relatives, incl. Daddy, Mommy, Grandparents, Auntie/Uncle, Cousin.
If he can perform the same in his daily life in the interviews, I think he can be easily admitted to the schools. However, unfortunately, he always refuses to say anything in front of strangers.
