Sassy Stacks of Circles STEM Toy

From 6 months. Pulling rings off a post comes long before putting them back on, and this toy is happy to be played with either way. The post is straight rather than tapered, so rings of every size slide on in any order, which spares a baby the frustration of a "wrong" answer while they practice aiming. Each ring carries a number, which gives you something to count aloud together. It is BPA free and wipes clean, and at well under $20 it is an easy add-on gift.
