My son had a little tree in his room since he was a baby and I never had a problem with it. He only had a few ornaments on that I (and later HE) picked out to put on it and then I put it out of reach in his room so he could only look at it.
He's 5 now and still has the little tree but ever year I warn him that if any the the ornaments are missing (ie, I see him playing with them) that I am going to take the tree away.
Children and Infants have been around Christmas Trees and Ornaments for 100s of years -- long before warning labels -- and we all turned out ok. Just be a good parent and use you head and it will be fine.
Edit: Oh, just to add my Son's tree is only about 20" or so. Just a little table top tree. I am not sure what size you were looking to put.

"I have always thought of Christmas time, when it has come round, as a good time; a kind, forgiving, charitable time; the only time I know of, in the long calendar of the year, when men and women seem by one consent to open their shut-up hearts freely, and to think of people below them as if they really were fellow passengers to the grave, and not another race of creatures bound on other journeys." ~Charles Dickens
