I like (vote) for compromise .... the gray camo for the back and your log cabin idea on the front. With the colorful center block surrounded by blacks and grays is outstanding. As the child grows, the colorful centers would be opportunity for learning color names. Gray is a popular color these days among young adults so it could be very "in". I do commend the mother for thinking of the step-daughter's accommodations as she prepares for her new baby.
