My 3 year old is beginning to take interest in letters! We practise a little every day, but I would like to very my methods a bit. We use traditional children's books but he is still not sturdy enough to read full words on his own and gets easily bored with the repetitiveness of the "easiest" books. We have tried reading eggs and teach my monster to read, but he (and I to be honest..) find the a bit tame. Do you have any recommendations on other learn-to-read apps I can try?
