At your daughters age I would not make too big an issue out of this, most people have one breast slightly bigger than the other, as her 'hormones are only just kicking in' then this may even itself out in time, what you don't want to do is worry her and make her self conscious , just keep and eye on it and if it is very obviously bigger when she develops more then mention it to your family doctor.
