I have recently come across some gorgeous App stories that my children love They are a collection of stories following a dog called Oto (there have also other books with a bear called Lina). You can listen to them in Spanish or English and you can record your own version of the story which is sweet. Often Spanish books for early readers have the joined up writing which makes it hard to find books for my daughter to practice with since she is learning in the UK with the separate letters. These books are great for her to practice her reading and my 3 year old loves them too. Great!
