I have 2 Munire Newport cribs & b/c of the size of the room, they are back to back with a short side against the wall. So, the other short side faces into the room & both have that warning sticker/label on the bottom. I thought it would peel off easily but I went to take off one & found that it did not, little pieces of the label came off at a time, etc... I don't want to have to scrape at it or use anything that will affect the finish- any tips on removing that label???
