This is a definite and emphatic no!
Weighing children at school equates to throwing a bunch of dishcloths to a person whose house is flooding. My plea is to take a step back and look at what’s causing the flood.
Don’t blame and shame people with a genetic predisposition to gaining weight, dropped into today’s environment that promotes energy-dense, nutrient-poor food relentlessly.
A better strategy is to nourish children while they’re at school, especially when the school’s in a socioeconomically disadvantaged area. Provide school breakfast programs that fuel children’s brains so they can concentrate on learning, rather than being distracted by hunger. Offer after-school homework clubs that provide supervision, tutoring and specialised help in subjects children need more support in, plus creative activities and nourishing snacks.
If we really care about children and their families, let’s provide a leg up, not a “fail” on scales.
