Think about your child's whole 'reading diet' - both reading themselves and being read to.
In school, there will be books / texts that are read to the whole class - perhaps a story book or poem they are using for English, or a book of bible stories in assembly, or some information about castles, or even the menu for the day...
Then at home I am sure you share books as part of your daily routine, as well as incidental reading of labels and boxes and packets.
None of this is limited by the fact that your child will ALSO have direct teaching of phonics (rather than having to intuit the phonic code for themselves, as early 'self taught' readers like my DS, or 'whole word' readers had to before it was realised that teaching the phonics code directly was more efficient for more children).
the parts of their 'reading diet' that ARE phonics linked are reading within the daily Phonics lesson, and your child's reading scheme book.
UNLESS your child has no reading diet other than their Phonics book and lessons, then there is no problem of 'feeding their knowledge of words, language and stories'.
It would be a VERY rare school where a child didn't have a wide exposure to books and stories daily in school. Just make sure that you as a parent are supplementing that with library books, own books, reading street signs or cereal packets etc etc at home.
