Tasty multi-vitamins or drops?

[Tun55]

Hi all
I'm completely fed up. My kids find milllions of excuses to not take multivitamins. I have 11 yr old twins and a 4yr old. The twins are absolutely driving me mad, I have all sorts of multi-vitamins - chewables, syrup etc, they make excuses and get away. I even found some chewables in the bin.
4 yr old is ok with the syrup but I was wondering if there is a easy way out for the whole lot. Anything they might really like or drops that I can add to milk and get on with my life?
Although we eat a lot of fruit and veg, we are a vegetarian family, so my kids need multi-vitamins.

Bumping for responses...

Can you still give the older ones drops by syringe or spoon? It’s done and swallowed so at least you know it’s done in one go. I know that’s a lower dose of some vitamins than you’d usually give to an 11yo, but if you look at the back of the packet there’s not a huge amount of difference, and then at least they’d be getting most of their rda!
