Bouncers are discouraged on the principle that they are disrespectful to a baby’s true emotions, as the object is to make him zone out and stop annoying you. RIE is philosophically opposed to anything that disrespects a baby, including not only sippy cups and high chairs but also baby gyms, baby carriers like Björns, baby swaddles, and baby walkers, which Gerber, who had quite a way with words, called “a moving prison.”
What else is prohibited? How about toys? “Children don’t need toys,” says Solomon. “Almost all of the toys at RIE can be found in somebody’s cupboard.” No rattles either. According to Gerber, “Rattles are an adult idea: you pick up something, and it makes noise. Why does it make noise? Because some adult put something into something.” No mobiles. “Mobiles are intrusive—the infant has no choice. Who chose the mobile? An adult.” No pacifiers. “The pacifier is a plug,” Gerber once wrote. “It does stop a child from crying, but the question is, Does an infant have a right to cry?”
