Do books and art supplies count as toys? If so, I would add a stuffed animal or doll. If not, I would include something to push or ride and a play set (Playmobil, Little People, Legos, animals, etc.).
Of course, the above assumes that the LO has access to a lot of non-toys. DD spends at least half of her time playing with things other than toys (kitchen items, boxes, pillows/cushions, etc.).
