Tim’s teething hack sounds pretty good to me on this hot summer afternoon:
We fed our daughter frozen blueberries to help her with her teething. She liked the taste and texture and since they were frozen they helped numb the pain. Best done when in a high chair with a bib…blueberries can stain pretty well.
If you’re concerned about choking, several folks have suggested Munchkin mesh fresh food feeders (see the related hack).
