Sassy Stacks of Circles vs Fisher-Price Baby's First Blocks: Which Is Better for Your Baby?

Between six and twelve months, babies learn through repetition, sensory feedback, and trial and error. Stacking rings and shape-sorting buckets are perennial favorites because they fit small hands and produce visible results. The Sassy Stacks of Circles and Fisher-Price Baby's First Blocks both target this age window, but they build different skills. Here is how they compare so you can pick the one that matches your baby's current stage.

Quick pick: Sassy Stacks of Circles. Best for babies starting around six months who need low-frustration stacking and size exploration. See it on Amazon (affiliate link).

Sassy Stacks of Circles

Sassy promotes this nine-piece set as an early STEM toy [Sassy]. The kit includes eight rings and a straight post with a wide base. Because the center hole on every ring is the same diameter, a baby can slide them onto the post in any sequence, which removes the frustration that comes from a required order [Sassy].

The rings differ in outer diameter, naturally introducing size comparison. Several feature textured surfaces and high-contrast black-and-white patterns aimed at younger babies whose vision is still developing [Amazon.ca]. Sassy has produced developmental toys for over 30 years and designs products alongside child development specialists [Amazon.ca].

What it teaches. Sorting by size, basic sequencing, early cause-and-effect awareness, and confidence through repeated success [Walmart]. The set works hands and encourages the grasp-and-release motion that later feeds into self-feeding and drawing.

Main trade-off. There is no shape-sorting component. If your baby is fascinated by fitting objects through matching holes, this set will not scratch that itch. It is purely a stacking and spatial toy.

Fisher-Price Baby's First Blocks

This Fisher-Price set pairs ten chunky, brightly colored blocks with a plastic bucket. The lid has shaped cutouts, so a baby can sort each block through its matching slot. Remove the lid and the experience becomes a simpler dump-and-fill game, which is often what six-month-olds gravitate toward first [Amazon].

What it teaches. Color naming, shape recognition, hand-eye coordination, and the problem-solving required to rotate a block until the shape lines up with its opening [Amazon]. A Navy and Fawn colorway listed on Amazon carries a Global Recycled Standard certification, indicating more than 50 percent recycled content [Amazon].

Main trade-off. The shape-sorting task sits on the harder end of what a six-month-old can manage. Many babies at that age will enjoy dumping blocks out and tossing them back in, but the intended sorting skill usually clicks closer to nine or ten months. Parents should expect a slower ramp to the full play experience.

Which One Should You Buy?

Choose the Sassy Stacks of Circles if your baby is right at the six-month mark and you want something they can succeed at immediately. The identical center diameters take guesswork out of the equation and let even the youngest babies participate in meaningful play rather than watching an adult demo [Sassy].

Choose the Fisher-Price Baby's First Blocks if your baby is closer to eight months, already stacking one object on top of another, and beginning to show interest in how shapes relate to spaces. The bucket format also makes it a practical travel toy, since the container keeps all ten pieces in one place [Amazon].

Neither toy requires batteries. Both withstand the drool, throws, and chews that define the first year. If the budget allows, keeping both within reach gives your baby two different thinking challenges to rotate between as they develop, which mirrors how infants learn: short bursts of repetition across varied tasks.
