Stack, nest, pour, and build: the Loulou Lollipop Stacking Cups grow with a child from bath-time play all the way through early counting and sorting, well past the age most stacking toys get outgrown. Drainage holes built into the base of each cup mean they double easily as bath toys, letting water pour through during play rather than pooling inside and turning into a mold risk the way a solid cup would. The set nests compactly for storage, taking up a fraction of the shelf space a typical stacking toy needs, which makes it just as easy to pack for travel or daycare as it is to store at home. A versatile, long-lasting toy that moves fluidly between the bath, the living room floor, and the beach, rather than being confined to one single use, the kind of toy that earns its shelf space for years instead of months.
