Except for Kacio. One of the things that is unique about Kacio is that he will be growing up here, in Poland, as his language skills are developing from toddler to young child, unlike the others. He has heard and understood Polish from day one but he still knows that his Mama speaks English. He speaks to me in English. All the kids do. But the amazing thing to me is that he responds to Martin in Polish. The other kids do not. In fact, if Kacio is speaking in English to Martin and I, and he thinks we are not listening or he is not getting what he wants (which is more often the case) he will turn to his Tata and ask for it, in Polish. This has been amazing to see. I am hopeful that over time, as the older children are able to better express themselves in Polish that they will also begin to respond back to Martin in Polish. Nothing would make him happier, I know.
Lastly, and most importantly, for any young child of course, is just to be talked to in general. Kacio gets plenty of that, in both languages. And he, in turn, never stops talking. All. day. long. ;)
I made this video for Uncle Freddie, but he's just darn cute, I had to share it here.
