I think Carters and Osh Kosh have that kind of sizing. They have toddler sizes 2T thru 5T and then they have kid sizing from size 4 up.

No idea what the difference is though...I believe the diff. between 24 months and 2T is length, so I'd imagine it is similar with the toddler and kids sizes. I wonder also if the toddler pants, for example, have the adjustable button waists, and maybe the regular sizes don't have that.

eta: I looked on Carters website, and there are shorts that they have in both toddler and kid sizes, both have the adjustable waists, so that's not the difference.

From the site, toddler sizes:

2T 34.5 – 36.5 in 29 – 31 lb
3T 36.5 – 38.5 in 31 – 34 lb
4T 38.5 – 41.5 in 34 – 38 lb
5T 41.5 – 43.5 in 38 - 42 lb

kid sizing:
