where can i find a standard clothing measurement chart for babies and children?

i am after a standard clothes mearuring chart so my customers can get an idea of what sizes match which age. i put sizes on them but takes alot of time to do and would like to cut the time taken measuring all childrens clothing. i know sizes differ between brand but if i can offer a standard chart give customers an idea this would be a great help.

SIZE WEIGHT HEIGHT
0-3 Months 6-12 lbs. 20-24″
6-9 Months 13-18 lbs. 24-26.5″
12 Months 18-22 lbs. 27-28.5″
18 Months 22-26 lbs. 29-30.5″
24 Months 26-29 lbs. 31-33″
2T 26-29 lbs. 33-35″
3T 30-34 lbs. 35-37″
4T 34-38 lbs. 37-40″
4 35-39 lbs. 39″
5 37-41 lbs. 42″
6 40-45 lbs. 45″
6X 44-50 lbs. 47″
7 60 lbs. 49″
8 66 lbs. 52″

This seems consistent with the clothing i buy for my child. She is 11 months but weighs 24 pounds and wears size 18M. Here is the site that i found it on.
