These therapuetic stuffed animals are filled with all natural grains like flax seeds as well as a variety of herbs. Lavender, Chamomile, Vanilla, Elderberries, Peppermint, Spearmint, Rose Hips & Petals provide a soothing scent to help your child drift off to sleep. Simply warm the stuffed animal in the microwave for 10 second increments until warm (microwaves vary, adjust time accordingly, adult supervision required, product will burn, wipe clean with a damp cloth, do NOT saturate). For a cold stuffed animal during the summer months keep it in the freezer until your child needs a cool refreshing cuddle!
