theses are silly slippeez and the large is 2/3. i found them on ebay and walmart. Please let me know if they are a large size 2/3 or a xs/s because thats a big difference. the picture shows large slippers.
They might be a little to big for a 1 yr old, but a toddler should be ok. The size is 2/3. My mom brought these for my son when he was 3, he's now 5, he could fit then then but no way now!
