According to the University of Michigan Health System, you will know that your child is getting enough sleep if they can fall asleep fairly quickly (within half an hour), can get up easily in the morning, and are able to stay alert all day without a nap. But how do you make sure that your child is getting adequate sleep? What do you do when your child has sleeping problems? According to a new research data, the consumption of omega-3, either from food or supplements, may help children get better sleep. The preliminary data from the Oxford University DOLAB study assessed the relation between omega-3 levels and behavior and sleep patterns.
