How does this lotion work to help babies and toddlers sleep?

• The key ingredient in the lotion is the deep sea magnesium we use. It's a unique form of magnesium that can be absorbed easily through the skin. Once it gets absorbed, this magnesium helps to regulate GABA, a neurotransmitter that naturally calms us down and helps us get deeper, more restful sleep. 
• The magnesium also helps with restless legs and growing pains (which can sometimes wake babies or toddlers up in the middle of the night without us knowing).
