To add another consideration here, if children are too young to spit out seeds, they are still too young to eat all but the tiniest grapes whole. Grapes present a major choking hazard to young children, and need to be cut into safe sized pieces before they eat them. Unlike soft, starchy foods, they will retain their shape without softening or dissolving if they block the airway, a characteristic which increases their riskiness, along with their smooth curvature that lets them easily slip down unintended.
They are yummy and refreshing treats, but do need to be served with caution. If you have to cut them, it doesn’t take that much more time to pop out the few seeds that are in the seeded ones.
Having young children, you were likely to already be well aware of this, but I’d be remiss if I failed to mention it in case someone didn’t already know.
