DD is 10, give or take a week

Over the past few months her breast buds have started to develop and she has become a lot more hormonal (a whole other thread )

I have noticed her left breast/nipple/bud is developed more than the right. In fact, the right is still pretty much flat. Is this normal?

I really want to have a good look at it but I don't want to make her self conscious about it.

Any insight greatly appreciated
