Our daughter love to write, that's one main reason why I created the kids e-Connection blog. I made her stopped though when she started going to school again. Now that she's off, she asked me to write on her blog which I permitted.
I bought her a Diary and some papers to write on so while she was on break on blogging, she was writing short stories (I'll post it one by one next time for you to read). She also write on her diary everyday. For a six year old, she writes very well. She sometimes asked for spelling of really hard words but other than that she writes really good for her age. I believe that encouraging your kids to write an early age helps their vocabulary a lot.
Below is the letter she wrote for Santa and below that is my sons. Sissy taught baby brother what to write.
