For the most part, food storage containers should last for years. If you have glass containers, you’ll want to replace them if they have any cracks or chips. Even if the container doesn’t leak, it’s still a shatter risk or could have a jagged edge. If you have plastic containers, you should replace them if they get warped. Stains can also signal a decrease in the integrity of the container. As long as you’re properly cleaning and caring for your containers, they will definitely last through the baby food stage.
