A couple of things hun. Firstly, what do you mean by 6 feeds in a day? Is that in 24 hours, or do you do night feeds as well as 6 during the day? Because 6 feeds in 24 hours is not a lot. Newborns usually need 8 - 12 feeds in 24 hours. Some do manage on 6, but it is not common. Also, you are best off feeding from the same side until it seems empty. Often babies only take one side per feed. It is fine to offer the second side, in fact you should offer the second side, but make sure she's finished the first side first.

Otherwise the things you are talking about sound normal. Wet nappies are the best sign of enough milk. How many wet nappies would she have in 24 hours - and are they cloth or disposable? IF there are plenty of wet and dirty nappies then I don't think you have anything to worry about.
