I've just done this a couple of days ago and will be getting the jewelery back next week.... Hope DH doesn't see this post as it's a surprise for our wedding anniversary! I ended up using clay-time (dot com dot au) as I was really unhappy with smallprint I drove 45mins each way to see the lady when DS was 8 weeks old as she told me she could do what I wanted and when I got there she said she couldn't! No apology from her either grrrr anyway the lady from clay-time has been really great plus cheaper woohoo They also recommend 4 months but when I originally saw the small print lady she showed me a pendant with a 10 week old's print on it and it still looked good. So I took DS's at 10 weeks and whilst I couldn't 'see' his print in the clay I think the pendants I am getting will still be cute as it'll still be an impression of his little finger kwim anyway I'll let you know what they end up looking like next week if you like
