You mentioned looking for audiobooks with text. In case this helps:
www.librivox.org has audiobooks for free, recorded by volunteers. Almost all of the books are read from online texts which you can also download for free. Most books are in English, but there are lots of other languages. There are lots of children's books too, all older because everything's in the public domain. (Think
Heidi [in English and German!].) The volunteers often take suggestions, if you want to hear something that hasn't yet been recorded.
(I ought to know; I volunteer there myself.)
Children's books in Dutch (text links are on each book's page):
Librivox catalog - Children - Dutch In Spanish:
Librivox catalog - Children - Spanish Just to give you an idea.
