The TS credits are separate since 1/1/2007 and you will receive separate checks at your TS meals showing adult and child credit usage.
The CS credits are not separated, but the CMs at the outlets are supposed to enforce the separation of the orders. In other words, if you have 2A/2C on your card, they are not supposed to let you order more than two adult meals -- upon penalty of termination, or so we're told.
