When can i start to give milo drink to my toddler?

You mean milk?: You can start with mild after 12 months. This is the time when most babies are eating enough food to otherwise support their nutritional needs.

Depends: Milo is a chocolate/malt milk that is available in various forms around the world. It is cow milk based and has chocolate proteins so introduction after a year of age is reasonable. It is not tolerated by kids with cow milk, gluten or chocolate sensitivity. There is some caffeine in the product so if used it should be limited.
