The Luna Weighted Blanket for Kids ($55, originally $65) is made with 100% cotton and is designed to help reduce stress, anxiety, and insomnia, and increase melatonin and serotonin. These come in a variety of patterns and weights, but the company recommends a 5-pound blanket if your child weights 50 pounds or less, and a 10-pound blanket if your child is around 100 pounds.
