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.
The average size for a 12 month old shoe is around a 3, my son's first shoes were a 6 at 12 months. So it's really hard to say what size shoes a 12-18 month old would need, as they're all diferent and all grow so fast.
