Pre-school and primary children love reading with an adult. Being away from your child due to work or travel commitments need not be a hindrance: try distant reading.
Distant reading can be done by telephone or video. Get two books out of the library and read them together. Alternatively eBooks on a single account usually enable you to down load and pay for one book and it is also available on a second device. It doesn’t have to be long, 5 to 10 minutes each day per child is a brilliant investment.
With older children, find out what they are reading and try reading their books. Then you can find out what they are into plus it will give you a common interest that you can discuss.
