MG - DD1 is a huge sook as well. The slighest sight of blood and she almost feints. We have to hold her up and get a washer for her face to calm her down lol. I found explaining everything to her the best way. The nurse was really surprised at how much she understood about the needles, but there was no way she was going in there without not knowing. Once the first needle went in and she realised what it was all about she was ok. I had to hold her leg pretty tightly, but considering, she did really well. We just had to make sure the bandaid was a big one to cover up any blood!
