This is Level 2 of The Monti Kids® Program, a three-year curriculum designed by Montessori educators. When you subscribe, you'll receive support for baby's learning with a delivery of authentic Montessori toys and developmental activities every three months, plus expert support. From 4-6 months, as your little one’s movements become intentional instead of reflexive, there’s so much they can explore! We’ll help you introduce activities for tummy time and sensory exploration in this Level.
