Review (3/5): Works but has its drawbacks
Overall, the product worked for us and our toddler was sleeping better. I stopped using it because of the side effects.
I stopped using it after 2-3 weeks as he started developing random bruises on his legs, even from the slightest bumps against the high chair when we would put him in it. Our doctor said that easy bruising was likely to be related to the magnesium intake. After we discontinued the use, the bruises went away.
