Several. Basic hygiene lessons on hand washing after toileting, brushing teeth everyday, healthy foods, water vs soda and get out and play. Don't forget safety talks about seat belts, strangers, social media caution. Limit TV/Screen time to no more than 2 hours a day. http://www.healthline.com/health-slideshow/healthy-habits-mothers-should-teach-kids#1.
