That is a great way to see if your child will respond and enjoy!
Reading Eggs is a program the boasts making reading easier for children to learn. Parents and teachers have the option to register for a free trial and no credit card information is required so you can decide whether or not this is something that will work for your children. After the free trial the subscription costs $75.00 for a year and 49.95 for a month. So I would definitely take advantage of the trial and make sure your child would benefit before investing the money.
