Bring dynamic, wobbling fun to playtimes with the Balancing \u0026 Stacking Tree (10440) educational toy. Packed with endless learning moments, this colorful building set lets toddlers aged 18 months and up learn skills and have fun with the baby owls in their cute tree house.

This preschool playset is designed to promote problem-solving skills and patience as toddlers work out how to stack elements so the tree balances. Animal-loving toddlers can add extra bricks to steady the tree or can simply explore the tree house with the LEGO DUPLO owl figures.

Using the day and night toy brick, grown-ups show toddlers how these nocturnal bird toys for kids are active at night but then sleep in their eggs by day. Toddlers practice their fine motor skills as they open the tactile eggs and their color-sorting skills as they match the right owl to the right egg. This nature toy reconfigures in lots of different ways to stimulate toddlers creativity and perseverance skills.
