DS2 is 3 year and 9 months and knows all the letters and is trying to read (signs, books, cereal packets etc). He has learnt them all by their name rather than by sound (thanks to a tablet!) and gets really cross if you try and give him the sound rather than the name. Just wondering if I should keep trying to correct him/point out the sound or if there is any way to teach him to read using the name rather than the sound. DS1 is in year 1 and slightly behind with his reading so really keen to try to support DS2 with his, especially given that he is keen and wants to learn.
