The Fir Tree:

The book includes famous fairy tale The Fir Tree by Hans Christian Andersen fully illustrated all-color (11 color illustrations) by Maria Tsaneva and adapted in corresponding English-German paragraphs.

The book is an excellent way to read Paragraph by Paragraph Translation along your kids.
Your little one can follow along as each individual English paragraph is paired with the corresponding German paragraph.
The paragraphs are not long, so there is no need to do a lot of back and forth to see the German translation and the English text.
The text is relatively simple vocabulary and grammar wise, but not very simple at all, so for beginners this should be a great challenge.
