Choice A is incorrect because parental involvement is important for safety and proper technique. Choice C is incorrect as waiting until closer to adolescence may delay the child's ability to manage their diabetes effectively. Choice D is incorrect as reaching injection sites is not the sole criteria; proper technique and supervision are essential.
