will you have a helper to do the laundry for you?
i would say, if you are doing it all yourself without help, then i would buy a few more...
if you have a helper, you'll find that the baby grows so quickly, you won't need too many...
my son is now 17 months old... i just sent about 5 bags of clothes to my friend... some of the things that i bought my sone wore only once, and some he didn't wear at all!!!!
the good thing is i'm expecting again so, hopefully, the next one will get to wear them too...
teh other thing is, you may find that the pieces you think will be the best will be ones that for one reason or another, you don't like at all!
