I have two skinny children and most pants are either too big or too small. The trousers of this brand are as age-appropriate as possible. So my 3 year old wears 3T. When my oldest child was 3 he wore a 3T and with other brands it's usually a size 2 and sometimes a size 4. They always seemed to work. And the latter are given to cousins.
