A toy for all ages!

My 1yo took on it straight after out of packaging. This thing is HUGE (make sure you have the storage space for it)!! and stacking the pieces is such great practice for squatting and standing up for bubs who are hesitant to let go to stand on their own. My 6 yo also loves discovering the names of polygons and their corresponding number of sides. We use it for building, for rolling, for learning, colour and shape recognition, and we use the stacking dowel for our other wooden toys such as rings. We love this piece!!

My 12 month old loves unstacking and restacking the pieces and it’s great to develop fine motor skills.
Love love love it.
