Anong mga fruits ang best pakainin sa mga toddlers na may common cold?

I know that eating fruits that are high in vitamin c (like citrus fruits) are great for PREVENTING common colds. Though, I'm not sure which fruits are beneficial for when someone is suffering from the sickness. Maybe consider water with fresh squeezed lemon juice? Or perhaps low sugar content yogurt, since the yogurt has probiotics that can help boost the immune system!
