Sleeping is one of the more private aspects of parenting; it happens in a quiet room, whereas eating is a more public aspect of parenting. Other people can see it and compare it to what their kids eat.
Sentiment: POSITIVE
I've seen the same thing emerge in the research around the interaction of sleeping and moving and eating: if you get a good night's sleep, you are significantly more likely to make the right choices about what you eat the next morning, you're more likely to work out, you're more likely to get a better night's sleep the next night.
