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.
DS was 6 lbs 12 oz and wore newborn diapers for a good month, maybe a bit more. He also wore preemie clothes for the first month or so! Unfortunately, it is not ALWAYS good advice when people tell you not to bother buying newborn diapers, or when they tell you to only buy 0-3 month clothes and skip the newborn sizes.
