Size small, 4-8 months. Our baby started in these around 5 months and would have fit in them past 8 months. She’s relatively small. This didn’t get much use from us but it’s a good summer weight and good as a transition swaddle. Good condition. No flaws on zipper or seams. Slight piling because it’s a soft frantic. Smoke free home. We use unscented laundry detergent and have a labradoodle.
