Oh yes, I found some bamboo baby socks for DD2 - oooh they are sooo soft and silky feeling. I went back to get some more and apparently everyone else thinks so too cos I couldn't find any more! I didn't realise it was available in lady clothes - will have to keep an eye out for them!
Marydean, I was shopping in Coles today and they had kids socks from bamboo by Rio in there - first I'd ever seen them too - but I didn't see if they had any in the baby section though - might be worth a look
