No it’s a cognitive framing thing. The concept is to make a toddlers tumbles into not a big deal for them. I think it is also in part an overreaction to the common “oh you poor baby” response which is thought to encourage children to be upset when they fall. I favor the Montessori guide approach of observing|ignoring and giving a kid a chance to make up their own mind to ask for help or deal with it themselves. The optimal approach probably depends on the kid.
