I'm kind of in the same boat as you (verita), I want to expose my 2 year old to the Chinese language because I too feel it will be mind broadening and I know at this age she will soak up anything I can give her. But I to don't speak it, read it or even hear a lot of the differences in the sounds so that is why Im going with the Chinese Little Reader curriculum.
I'm not expecting her to be able to speak fluently but I hope she will overtime hear the different sound and learn some of the words and have the confidence to learn more of the language later in life.
Just today I bought the Chinese curriculum as I have been doing the trail for the last 12 weeks. First my daughter wasn't interested in it at all but now I can see she is taking some of it in. so I feel its worth a shot.
I did read somewhere that its best not to try and pronounce the word unless you actually know it as it can be a distraction and incorrect for the childs learning. Its also best not to translate into English (or Polish) as they are hearing the Chinese language as the languages are so different and the child will be tuning into the tone of the new language. Just trust they will learn to decode it themselves.
But that doesnt stop you from trying to still make it multi sensory by touching the childs head when it show the Chinese word for head, or having the certain food ready for the child to touch and taste as the word flashes up. I'm going to try and do things like that along the way.
Also Im going to make a Chinese word doll for all the body parts and draw the symbols on all the dolls body.
I also try and show my daughter Chinese songs with the words written below,
