This is an interesting question.
I went through my catalog box, next to the recycling pile, and pulled out all the Catholic publishers’ catalogs that I could find.
Didn’t actually find any Catholic kid’s magazines.
HOWEVER, many of the publishers had inexpensive books for kids, in both English and Spanish, with a variety of topics.
It’s a lot of work, but you could order a bunch of books and then distribute them on a monthly basis. It depends on the maturity of the kids involved and all that. Coloring books; lives of the saints; Our Lady;
Here are some of the publishers. You might want to get their catalogs and browse until something “moves you”.
www.ignatius.com see page 6 of the Christmas insert of the Fall/Winter 2006 Catalog
Catholic Answers catalog pages 32, 33 etc … stuff for kids
www.booksforcatholics.com page 26 summer 2006 catalog
www.catholicbookpublishing.com pages 40-55 tons of stuff for kids … Spanish and Englsh. call 877-228-2665
Anyway, before they “time me out”, try those.
Let us know what you end up with.
