Transition from liquid vitamins to chewable. When did you stop the liquid vitamins and go with the chewable kind?

I think my son is old enough and I want to do the tranition soon. At what age did your DC start chewable vitamins? What kind are using?

Edit: Ooops wrong forum. Is there a mod that can move this to parenting for me?
