haitang,
if i remember clearly, the $169 is not thick wood..i think the thick wood one cost $299
ahNah,
for pampers and huggies newborn, 1 pack is 24 pcs. for newborn, can use up to 5kg.
for S size, can use between 3-8kg. so if u estimate ur bb will be more than 3kg, than perhaps can stock up S size more than newborn size. but usually u wont know the baby size until later on..
