Parent Map presents "10 Montessori-inspired design ideas for kids' rooms."
Montessori inspired? Child-sized furniture and tools that help a child with independence. Dedicated work places. Floor-bed rather than a crib. Practical life activities such as cooking. An aesthetic emphasizing simplicity and beauty. Natural materials (eg., wood vs plastic).
Montessori teachers will cringe at some of these ideas, but I found some good ideas for parents.
