Are clothes manufacturers making baby clothes on the small side or something. DS is 4.5 months and is 15lbs and very long. Even still, I was shocked this morning to find myself having to put him into 6-9 month clothes - the only 3-6 things that fit him are the odd vest and sleepsuit. He is on 75th percentile so bigger yes, but not huge. Are there any other mums working this far ahead on the clothes front? I feel a bit sad actually, he's growing so quick.
