1. Wash the grapes thoroughly under running water to remove any dirt or residues.
2. Cut each grape in half lengthwise to prevent any choking hazard. If the grapes are particularly large, you can cut them into quarters.

4. Cut the peach in half, remove the pit, and then slice the peach into thin, manageable pieces that are easy for your baby to grasp and self-feed.
5. Arrange the grape halves and peach slices on a plate suitable for your baby.
