Cara, you asked me to explain why I keep telling you parents how much easier you could raise healthy “happy” children if you would make outdoor living a regular habit for your babies. Why? Because babies thrive out of doors, they sleep better, eat better, look better, play better, and learn better
Original RIE Manual
Toys should be sturdy but simple. I do not like busy toys. I like busy children manipulating their toys in many imaginative ways. Include objects that are safe and simple. These objects should be basic, able to be manipulated in many ways, and not requiring adult help or supervision. They should require the child to be active, not passive.
