My DS is smack bang on the 50th centile curve and has been since birth. He'll be 5 months old on Saturday and has grown out of his 6-9 month items and is well into 9-12 months. Is it just me or is this ridiculous? Surely the 50th centile is the definition of average, so logically clothes for his age should fit him? Are manufacturers being cheap with fabric, knowing that most people will buy a bunch of clothes for various ages before their children are born - ie are they cynically taking parents for an expensive ride?
