The walkers that many parents buy for their infants may do more harm than good, according to the Academy of Pediatrics, which has decided on banning their manufacture and sale. There is no evidence that these devices help infants to learn to walk independently; on the contrary, they say, they can delay normal motor development. Which of the following effectively questions the decision taken by the Academy of Pediatrics?
1) Apart from one or two reports of serious injury, the majority of infants who have walkers learn to walk eventually.
2) Walkers are usually bought by parents of differently abled children who are unable to walk normally otherwise.
3) A statutory warning would be more effective in tackling the situation.
4) Inflexible shoes designed for babies are more likely to hinder walking by preventing them from learning how to flex their feet to maintain balance.
