This information can be found stamped directly into the plastic of your booster, on the back or bottom of the unit.
The model number of your feeding booster will begin with a BO, 21, or 41. The date of manufacture will typically be noted as a date clock. There will be an arrow pointing to the month of manufacture with the last 2 digits of the year stamped on either side of the arrow. Some models may have a date code stamped on a sticker or label. In these cases, the date will likely be noted in YY/MM/DD format, followed by 2 letters.
