MIL thanked me for being a good mom

My mil on several occasions have thanked me for being a good mom, once she sent me a Starbucks gift card and in the message said thank you for taking such care of my two loves ( her son and grandson). She’s sent random texts saying thank you for taking such great care of my babies and today for Mother’s Day said thank you for being such a great mom to my grandson. I know she means well but it’s extremely annoying to me. Does anyone else find this annoying?
