Blowout sale!

http://www.zulily.com/ is having a BIG blowout sale in honor of Labor Day!! This has become one of my favorite sites for great deals on baby/toddler and other great items for moms to be and new mamas! They also have great deals on gear for baby.  So run over to Zulily.com before all the deals are gone!

Could someone please explain....

So I do not understand why there can't be a standardized baby clothing scale, I get so confused with every brand having a different way of sizing everything,  So Landon is roughly probably 14ish lbs now and he is almost 4 months old, but adjusted age of 2 months.  So while he fits in some 0-3 because it fits larger such as Circo from Target, but is in some 6 month when it is Carters????WHAT THE WHAT!! Why can't it be a standard thing.  Everything should either be 0-3, 3-6, or they should stick with 3,6 etc. Or just plain put the weight range.  I mean everything else baby is confusing enough why should clothes be too.  So now my 4 month/2 month old baby is wearing a 6 month old pair of pants because its from carters...I'm just saying...
