Yep we have cloth training pants (have only used cloth so don't know what the disposable kind are like). My DD is a bit bigger than yours at 10.5kg but she fits the Real Nappies training pants fine, even though they say from 14kg+
We also have some Bright Bots ones that my mum bought, there must be different sizes as the ones we have are size Large (says waist 55cm).
The Real Nappies ones can be bought from the Baby Factory (and probably other places but that's where ours came from) and are great in that they hold a whole wee without leaking which is great for the start of toilet training. The Bright Bots ones don't contain a whole wee but are padded enough to catch little dribbles if they don't quite get to the loo on time.
Haven't tried any other brands of training pants.
Hope that helps
ETA have just checked the Real Nappies website and their training pants are sized too, so you could get small which says from 9kg but that should be fine.
