My daughter did the Bayleys test at 22 months. You know, it really didn't give me any useful data at all! She enjoyed the puzzles and games, and we got a 1 page report that didn't say much at all. And certainly didn't give me a heads up that she was gifted! It wasn't until we did the SB-5 recently that we got that confirmation. I remember thinking that the Bayleys test was semi-useful in measuring age equivalent fine and gross motor skills, but beyond that, it didn't seem to me to be much of a giftedness measure - much more useful for occuptational therapy (but then again, we participated in the test as a favour for my s-i-l for training purposes, so maybe we got a distorted view of the test)... jojo
