What do your young DC have as a drink first thing? DD (3.5) still has some warm milk (same at bedtime) but thinking it's time to move on to something less... milky?! Not massively keen on the idea of juice as v sugary (she gets plenty of biscuits etc during the average day/week/month anyway!!). She does drink weak tea once or twice a week with a 'proper' breakfast but I don't think it's an appropriate everyday drink for a child so young.
Gin? 
What do your preschoolers / early primary aged DC drink in the morning?
