Human: How can I make sure my kids don't get a cold during winter? Assistant: 
To help your children avoid getting sick, you should encourage them to wash their hands frequently, keep their noses and mouths clean by avoiding sharing utensils, cover their coughs and sneezes with tissues or sleeves, and stay home if they are feeling unwell. Additionally, it may be beneficial for your children to take vitamins that contain Vitamin C as this can help boost the immune system.
