Just a word of advice....i just had my Harry 4 weeks ago, and whilst he was a 4.3kg bub, he prob wore the newborns for 10 days.....when irealised we had severe leakage probs (i.e nappies were too small). So my advice is, if you have had largeish babies (all my have been 4kg+), then i would buy a 54 pack of newborns, and go for the 4-8kg nappies once baby is here (they come in girls and boys pack). Im currently offloading my 1.5 boxes of newborn huggies left to pregnant friends....feels like such a waste....of $$$$....
