It is common for toddlers to seek comfort in extra milk during hot weather as their appetite for solid foods dips. While it is important to stay within the recommended dairy limits (typically around 300-400ml daily) to ensure they don't skip essential nutrients from solids, you can offer alternatives to satisfy their thirst. Keep water easily accessible, and provide hydrating options like coconut water, raisin water, and watery fruits to keep them refreshed without overloading on milk.
