Choice C is incorrect because the increase is usually close to 45%, not 50% to 55%.
Choice D is incorrect because the increase is usually close to 45%, not 30% to 35%.

“You should place your baby on her back when sleeping to decrease the risk of SIDS.” According to Mayo Clinic, placing a baby on their back to sleep is one of the most important measures that can be taken to help protect a child from SIDS1.
Choice A is incorrect because there is no evidence that SIDS is directly correlated to diphtheria, tetanus, and pertussis vaccines.
Choice B is incorrect because SIDS rates have actually decreased dramatically since the American Academy of Pediatrics issued its safe sleep recommendations in 19922.
Choice C is incorrect because while sleep apnea may contribute to breathing problems, it is not considered the main cause of SIDS1.
