My DS is five summer born and just started Year 1. He has always enjoyed looking at books with me and his dad from being a baby - lockdown meant we spent a lot of time reading books at home. Reading is part of our bedtime routine - two books every night - and he has an extensive home library which he enjoys looking at, e.g. kids encyclopaedias, Science and nature books etc.
In Reception he enjoyed getting to grips with phonics and practising reading at home letter by letter. Then over the summer we had a break from school and the regularity stopped. He is a very active child so most of our summer holidays were spent outside. Since returning to school, he just seems to have lost the love for it. The new head of year has asked that we do 20 to 30 minutes every day at home and he has a number of books that he has the option of reading but he simply doesn’t want to do it.
I have been really careful not to pester or nag as I don’t want it to create a negative association, so I’ve not said you must do this, and I’ve tried to avoid it sounding in any way like a chore. I’ve tried to tie it in with cuddle time in the morning in mummy and daddy‘s bed or with a yummy snack after school but he is just not interested and he’s very stubborn when he wants to be. He has said “I will never read at home”! 
His dad and I work and he attends after school club so the hours during the week in which we can read are quite limited. At bedtime he is very tired and gets easily frustrated, and I found through experience in reception that bedtime is not a good time to try and practice his reading. It works better me reading stories to him at that time of day.
This weekend we also didn’t manage to get him to read anything. I have not asked him today because I don’t want to make this into a big deal and put him off for good but I’m wondering how I can get the enjoyment back and make him want to do it. He was really chuffed with his progress in reception and enjoyed showing his reading to me but that seems to have gone. I know he’s not as advanced to some readers in the class, but I don’t think he’s too far behind the pack either (yet).
What can we do to support this? I’m a big reader. I have lots of books and I am trying to model reading when I’m at home, what else can I do? If you can relate please help!!!
