Hi Tina, it's true that sourdough starters that are generally well cared for can last a few months in the refrigerator without a feeding, but it will likely take 2-3 days of twice daily feedings at room temperature to bring it back to its normal activity level and aroma. Feeding it weekly will help it rebound more quickly and will offer reassurance that your starter is remaining healthy. Before you put your starter in the refrigerator, give it a feeding and then let it sit out at room temperature for at least 2 hours. This will help ensure that it starts fermenting before it cools down in the fridge.
