Hope you aren't delayed too much kabuk, have fun!
I've got a 5 vests and 3 sleepsuits in newborn (the vests look tiny compared to the sleepsuits though!), about 6-10 of each in upto one month and then the same again in 0-3. As I thought the sleepsuits looked huge compared to the vests in the newborn I got 3 tiny baby sleepsuits in the sales for about £1. I have no idea how big this baby will be, I was 'average', my sister was huge, my husband was slightly small. I'm also in a few high risk categories for an early birth, so they could be smaller than I think. I figure I've got enough to get by initially then there is online shopping and next day delivery if we are really short on a size.
