Thanks so much.
DD loves to read. She's read many of the usborne first reading and she now starts to read usborne young reading. When she was 3, I bought Childrens Illustrated Thesaurus (parragon). It was good but now, many of the words she asked me were not there, e.g., the words she asked me this morning: "stern", "ball" (not a sphere, but party).
I've to choose a dictionary for her wisely. If I get her a big/thick/difficult one, or a fancy/pictures/easy one, either will discourage her to use a dictionary.
Would an electronic one be a good idea?
