My daughter is 6 years old and she will start school next year. She reads very poorly, not by syllables, but by individual letters. For example, she reads the word "mother" letter by letter, adding one letter at a time. She attends developmental classes with great enthusiasm.
Perhaps this is related to the fact that she started speaking late, around the age of three. But I worry that she will fall behind at school, since all children start well prepared.
