Hey H.,
My 18 month old boy does the same thing with his eyes. He does it for attention because he laughs when we catch him. As for the not talking so much I would not worry about it. I speak Italian & sometimes french to my son and my husband speaks to him in english. He talks like crazy & makes sentences and all. He has over 100 words, not kidding. Everyone always told me that bilingual kids take longer to speak. That's not the case with my little one. He understand every language we speak to him and talks in all 3 languages. Remember every kid is unique just be patient and everything will come together.
