What kind of multi vitamins can I give to my 18 months old? Would love to know what is really good for them.

I'm giving both my kids 1yr and 3yrs old sambucol for kids. It can help to maintain a healthy and strong immune system and is clinically proven to be effective on Influenza and other viruses. Sambucol Kids Formula consists of flavonoids (natural antioxidants) with added Vitamin C and Propolis. It is suitable for vegetarians and vegans gluten free. My kids love the taste of sambucol and it is easy to get them to consume their daily dose of the vitamins. I usually purchase it from VitaKids at paragon singapore,Or you can purchase it online too. http://vitakids.biz/shoponline/index.php?option=com_mijoshop&route=product/product&product_id=507&search=Sambucol%20for%20kids&Itemid=563
