In medicine and statistics, gold standard test usually refers to a diagnostic test or benchmark that is the best available under reasonable conditions.[1] Other times, gold standard is used to refer to the most accurate test possible without restrictions.
My daughter was still in NB nappies at that age and she is almost 6 months now and still in her 0-3 months clothes and wee tiny shoes :-) She is in size 2 nappies now.Some babies are just dinky!llen is 13 weeks and is wearing size 3 nappies and 6-9 month clothes.
Report Abuse. My son wore 0-3 until he was 3 months; 3-6 until he was 6 months and he's a big baby (18 lbs 10 oz, 28 inches long). It also depends on the brand of clothes-UK stuff fits bigger than US stuff; Canadian stuff in the middle.ots of 0-3 month, some 3-6 month, and a few 6-9 month outfits...It all just depends on the overall size and not the month size. For example, my son grows out of everything length-wise before he grows out of it around the body. Plus, not all NB, 0-3, 3-6, etc month clothes are the same size.
