Is this an issue?

I remember before we adopted our girl from China someone told us that the least of our problems would be language. We were sceptical but with hindsight they were right. We took along some books with pictures for her to point at (things like food, toilet, bath, etc) and we also quickly found that sign language worked well. So pointing to your mouth for food, miming drinking from a cup for drinking and many more. Go for it, I really do think you will find that it is not your biggest issue.

A quick update on my post. I forgot to mention that we did learn the Chinese for toilet activities so that if the poor girl needed to go she could at least communicate the fact.
