Well, I'd just make
one and let him sip. I'm guessing he's using a sippy - I don't really know...

But when I said my guy gets 3 pks, I meant
in a whole day - not at a time.
The EmergenC fizzes (straight SA does not), so I don't think it's a good idea to force that stuff in any amount. Unless it's just totally fizzed out, I guess. I find it very filling though, so I like to let DS regulate how fast he takes it in.
If your guy is not using a sippy, can you give him some in a bottle? All fizzed out, I mean?
If he takes that, make another later on? Get up to what gives him runny stools, then back down a bit. That's the only way to know what amount he needs.
