Thanks everyone. I did see American Cheerios at Partridge's (same co. as Shepherd's) but I just can't justify spending £8 on a box of cereal! I found puffed wheat at Sainsbury's on Friday and my daughter seems to like it fine, although it tastes like cardboard to me. But it was the only low-sugar cereal I could find for her. I'll keep searching, though, and hopefully my mom will be able to squeeze some US Cheerios into her luggage this week.
