Feeding grapes and any other solid fruit or food is fine provided, those foods are chopped or made into small pieces, before feeding to the babies. What happens when the food are not made into pieces is that those foods will enter the baby's small throat and get stuck there. As the baby struggle to swallow the food, it gets lodged onto the throat further more until the windpipe is pushed close, reducing the amount of air going into the baby's lung. If help was not offered properly as was in the case of this infant baby, then within four minutes or so, the baby would have died. So always remember to made the foods into smaller pieces before feeding baby any solid food. Sometimes, it is better to let the baby eat liquid food until they are much older to handle food by themselves.
