I just wanted to post an update in here about what has happened since I started this thread. I decided to go and see the midwife at the hospital and get her opinion on everything including getting her to check my food diary which I'd kept for about a week. It's $30 but I really wanted another opinion and this is the same midwife that we saw until DD was 6 months old so I have complete faith in her and wanted her opinion. Anyway......she weighed X and she was 9.7kg!! That's 1.4kg more than the GP had weighed her at the week before. There is no freaking way DD could have put on that amount of weight in one week, the measurement must have been simply incorrect. GP weighed her by getting DH on the scales, then getting DH to hold DD and subtracting. The midwife was really annoyed as it turns out she is on the 25th percentile for weight and length and 50th for head. She said that is perfectly fine and looked at our food diary and said that was great for a toddler her age and the GP clearly doesn't understand about genetic disposition (I think that's the word) and him saying that due to her birth weight she should be 10kg was just wrong. So I left feeling SO MUCH BETTER. You guys had all already made me feel heaps more confident about the whole thing but now knowing that her weight is okay I feel so so relieved.

Thanks so much for all of your lovely comments.
