Who thought it would be a good idea?

Who thought it would be a good idea to measure most baby clothes in just weight? If you don't have children, this will go right over your head. But if you do, you probably will know what I'm about to preach on.
Caveat: There are a few brands that do put in length but most are months and weight.
If a tag says 16-28 lbs, will it really fit my child? How about putting some length measurements on the tag. Do they think that I'm going to put a 20lb dumb bell in the clothing, then pick it up, and see if it bursts at the seams? Or do they think that I pick my kids up by the scruff and if they do an Incredible Hulk and rip through, then I know they're too big? Of course, I'm not going to do these things. (Well grabbing them by the scruff would yet again be a different post). I suppose they figure that I'm more likely to know how much my child weighs than how long. But since we go for check ups only every two to three months (b/c w/ 2 kids I no longer have the time to just pop in monthly for a weigh in and the Peds dept here would look at me like I had two heads if I did), I can only estimate either. So since I don't know either to be presise, why not offer both measurements so I can guestimate.
We've all seen babies and know that they come in different shapes. A 16lb baby could be a Michelin Man or Gumby! I happen to have had two gumbies. So if the label says 16lbs and they're supposed to fit in it, they usually don't because they're too long. That's why Andy was in size 6 diapers by the time he was a year old. I just bought Matt diapers that said 16-28lbs and he's almost too long torsoed for them. Even though I can still overlap the flaps.
Or how about Andy's easy-ups that say 16-34lbs. Honestly, that could be a one year old, a two year old, or a three year old! Andy is usually about 32 lbs but I keep ripping them b/c they aren't long enough from waist to bum.
To boot, Andy is solidly in 3T clothing b/c of length but needs a belt on everything to keep his pants up. I am not having my 2 year old sag with his "draws" hanging out! At least a couple of stores have the adjustable waistbands on their pants.
But back to my orignal point. Weight is so variable for babies, why not throw my a bone and put length on the labels too. I suppose if my kids were short and stocky, I would be complaining that everything is too long but not wide enough. But since I'm not complaining about that, I'll just keep complaining about this.
