Can you get Size by age

I've have still not received my jeans for my Grandson ... He's still asking about his jeans???????

Is a size 4slim the same size as a 4T ?? Can a 5yr wear a size 4slim?

Are the size 8 reg snap or button close? I know it usually depends on size (2-7 typically is snap, 8+ button) butmy son refuses to use the button😕
