Review on Luyusbaby Baby Sleeping Bag: Stay Comfortable with this 100% Cotton Toddler Wearable Blanket by Michelle Larson

I saw several reviews that the medium looked like it was for a 4 year old. But my son is about 31 inches tall so I bought the height at 36 which seems to be a medium size and is too small. I can't zip it up like a bag. It's a bit hard to tell from the photos but after washing it's a little wrinkled and just under 27 inches long but their own chart says it should be over 30 inches. The size is nowhere on the label. Maybe they just accidentally sent Small? Luckily I sent it back for a refund and am able to get a full refund. I was afraid to switch just like that - who knows what size is coming?
