Choose the location before the collection
Look for a place where the child actually spends time and where books can be stored appropriately. Make sure the basket or shelf is reachable and does not obstruct the room. Consider the formats you own; oversized picture books and delicate borrowed items may need a different arrangement. Avoid placing books only where they look attractive to adults but are awkward for the child to access. A simple shelf can work as well as a basket if it fits the space.
Keep the selection small and useful
Ask the child to choose one or two items, then add a familiar favorite and a book connected to a current question. Separate borrowed books clearly enough that returning them is easy. You can include different formats without assigning one as the serious reading and another as a reward. Do not add so many choices that the container becomes difficult to browse. If the child prefers a book elsewhere in the house, the basket should not become a rule limiting what they may choose.
Refresh after observing actual use
Notice which items are opened and ask whether the child wants a change. Rotate a few books rather than replacing everything on a rigid schedule. Keep a valued favorite if they still want it. If nobody uses the location, try another place or simplify the setup before buying more books. The useful measure is whether the arrangement helps the family find something to read, not whether the selection looks balanced, expensive, or impressive to a visitor.
