Id get 1 XS, maybe from the classifieds, plenty of time to grab a bargain
We only had Smalls and Amber was 6lbs 9oz when she was born (full term) and we couldnt use our cloth for 2 weeks as all the smalls were too big (we used tots and little lamb) so id probably get an XS to be on the safe side
and it can always be a little keepsake afterwards!
DD is 10months now and in Large WN wraps now lol they go through everything soo fast
Enjoy your newborn fluff shopping. I cant wait until i get to do that
think it will be a while yet
