The main focus in the early years is for children to be able to put words on paper and make stories.
For children to progress they need to be able to put their ideas on paper and start developing sentences, albeit very short ones in the beginning.
They need to "hear" the sounds and understand the key letters they are hearing, for example
I rt a ltr 2 mi mm
I wrote a letter to my mum
words like the are hard to write as a sound but they might write th or h or nothing at all.
If she wants to write the correct spelling, then encourage her to tell you how she things she should spell it, listen to the sounds and write the main letters. Then and only then, add in the extra letters.
IF children rely on adults telling them the correct words all the time, then they struggle in the class and are unable to work independently.
Filling in the letters comes later.
Its almost like when adults learn to write using shorthand, they use key strokes for letters but dont include any vowels. The English language is taught from these basics, the children write the phonetic sounds that they hear and then develop from there.
So try and not focus on the spellings with your dd for the time being, focus on the story and developing those ideas.
(I know its hard to do, and as adults we want our kids spelling words correctly from the start, but the system does seem to work)
