My dd is in reception and learning to write. In her school, they use books to practise their writing that have no lines (rules?) in them. According to the teacher it is the head's policy for the younger children to have unlined writing books. Older pupils do get books with lines.
I think that it would help the children when they are learning to write to have lines in their books, but I am not a teacher, only a parent! 
What do teachers (and other parents) think? Are lined writing books a help or a hindrance or neither for young children learning to write?
Thanks in advance for your replies.
