Linz, Tom hit 10kgs at 14 months. From memory Jack was 10 kgs at around 12 months. So your DD sounds really normal. I think 10kgs at 7 months would be well above average. I guess it comes down to birthweight, build and genes, as well as bf vs ff, when they start solids and how much they eat. Also those that crawl and walk earlier tend to slow their weight gain earlier too. So there is quite a wide range of "normal".
