What age for a medium weenotions

I only have the wraps but Luke is about 16 pound ish can fit in his small but med have also fitted since RNW whenever that was. He's longish too in relation to weight.

Thanks everyone. Mediums were weird for us. We never had any smalls but i remember her being in mediums for a short time then larges fit her quite early but lasted right until potty

That's exactly what happened here. Some mediums still fit but larges have fit M fine since around 6 months too so we barely needed to use mediums at all. (Except DnFs, M still wears most of her Ms and is only starting to outgrow some now)
