Tiny Babies and Cricket Sweaters

I found out a couple of days ago that my sister's friend had a tiny baby, only 4lb 13oz so I have now put down my cricket sweater knitting and started on a 10" baby cardigan, it is SOOOOOO small. I managed the back in an hour and the left front in about the same. It is probably the smallest thing I have ever knitted apart from dolls clothes and I am hoping to finish it asap as I want to get it sent off. I have a lacy number to knit too so never a dull moment!
