I think these are the right size for newborns to around 3 months old. I received them as hand-me-downs, and they're shaped like tabi socks. I put them on my daughter for her first meal ceremony. Both have non-slip grips, and the pink socks are from Afternoon Tea. They're very cute ◡̈⃝︎⋆︎* How about them for special occasions? ❀︎.(*´◡︎`*)❀︎
