I completely understand. I had my first u/s at 6w, and cause I thought I was further along I had to have another at 8w to check for growth. All was ok so at 13 w u/s I expected to feel "safe" but then I got told about the 20w u/s when they "really" tell you if your baby is ok. And I know of a friend here in BB who had to wait til 27w to be "sure" and even then it was only when her gorgeous girl was born that she knew everything was ok. And now my boy is born I worry about whether I started him on solids at the right time, and about whether it is ok to leave him with my mum tomorrow night, and whether he will know to not get into a car with drunk mates when he is 18.....

welcome to the wonderful world of being a parent!!!
