Nat ~ you must have been posting at the same time I was...LOL. I know what you mean with the little wee catcher bags. I had to use one on Samuel when he was 4 months old. A bit tricky aren't they. I had to give the doctor's a second sample a few days later because I managed to contaminate the sample the first time round (don't know how). I doubt anything is wrong with Em, better to be safe I guess.
