Spotty I think it depends why they've been sick. We went to TGI Friday's once, and DD threw up her whole meal, and was trying to eat more pepper batons between bouts, couldn't understand why we wouldn't let her.
If she seems ok then let her drink some water, and see if she can keep that down. If she does and is still up/ hungry in an hour you could dry her with some plain toast or something.
No Indian here, DH is still on soup!
