How much Vit C crystals for Toddler?

[Raspberries]

I've never been sure how much to give DD so I just end up not giving her the powder and find juices with Vit C. I'd like to give her some in crystal form like we take. The serving size is 1/4 tsp = 1250 mg. So what would that look like in terms of giving that to a 2.5 year old. Would I just want to cut that in half to 1/8 of a tsp? Less?

No expert here, but this is what I do...

I break open 500 mg of Vita C for Reid (he's almost three) and put the powder in his drinks. Sometimes I do it twice a day (if he's sick). This much C always makes his poo really, uh, soft. :shifty Sometimes it's so soft he don't realize it's coming. :( Anyhow, I think 1000mg is too much for Reid. He's 35+lbs.
