Begin encouraging healthy nutrition. Regularly consuming unhealthy and processed food is a risk factor for depression. The healthiest diet is one rich in fresh fruits, vegetables, healthy grains and nuts and cold water fish such as salmon. (Benefits of Nutrition)
Establish a routine of eating together as a family. Children who experience fewer family dinners are more likely to experience depression and suicidal thoughts. (Family Meal Vaccine Part 1)
Strive for family meals as often as possible, beginning as young as possible, to set good habits that will benefit every family member in the long term. (Family Meal Vaccine Part 2)
Promote adequate sleep. Poor sleep habits contribute to poor mental health. So establish healthy sleeping habits in your toddlers and preschoolers to ensure optimal brain development and mental health.
Limit screen time. Excessive exposure to screens (television, tablets, smartphones, computers, and video game consoles), especially at early ages, has been associated with behavior problems, increased aggression, lower self-esteem, depression, and more. The less screen time the better but definitely no more than 2 hours a day.
Practice authoritative parenting. Children raised by engaged, authoritative parents are less prone to depression and anxiety so balance the use of correction with encouragement for best results. (Parenting Styles)
