I don't buy a whole lot but usually I wrap each and every item separately (so if there's a series of books I wrap each book individually rather than putting them together in a single wrapped present.) just so it looks like more and they can have more fun opening more presents.
Does anyone do the same? I am feeling this year that it's a bit too silly to do it that way so I think I will consolidate some of them into larger presents (DD is 7).
