Getting ready for a two-week business trip, bald-topped Daddy shares his feelings with Abe: ``I miss you so much that my hair falls out.'' Sometimes, too, he says, instead of taking notes in meetings he draws the two of them fishing—just as Abe does, waiting at home. Companionably, both confide the effects of the separation, and then Daddy promises to be home when the crescent moon is full; Abe can watch it, and draw it, larger each day. ``You can always count on the moon, and...on me.'' Comforting, sensible, and crafted with care (it's especially good to find a picture book where the moon isn't full all the time), the story is nicely extended in bright, realistic illustrations where the pajama-clad preschooler—first seen wistfully hiding in the empty suitcase—confirms his closeness to Dad while he helps him pack.
