Hi Laura!
I don't think that what's happening to you is unusual at all.
I didn't personally lose the way you are but it was bizarre at times ... and it took quite a while for some body parts to catch up to others. I lost a ton off my waist before my hips, and the result was that no pants fit me for about four months due to that huge gap in the waistband of my pants (you could have parked a truck in it).
Some people actually lose on one SIDE before the other, so they end up kinda lop-sided! It all seems to even out in the end, though. It sure would be nice if the fat came off evenly, but we all need that dreaded word - patience.
Losing weight has got to be one of the most amazing adventures since a lot of the time we really don't have any control over what our bodies are going to do. We can eat right and exercise and the fat just seems to come off the craziest places!! Hang in there and I'm sure it will even out in the end.
