Going to the grocery store

This may be a dumb question but what do you do with the carseat when you go to the grocery store? Idk what to do really because he is 5 weeks old. Unless my husband or mom comes with me idk what to do with the baby. I cant bring the stroller and push a cart. So ladies what do you do with babies this young when you have to go grocery shopping and you are alone?
