Just bumping this thread.
Last night took DD to an after hours clinic for respiratory problems and the Dr rather casually mentioned that she had gynaecomastia and we should see a paed about it ASAP.

As far as I can tell that term applies to boys with breast development, in girls it's referred to as premature thelarche (premature breast development). Apparently it commonly appears between age 2-3.

DD is 2.5, I can't say that I've particularly noticed her little boobies before, you know what it's like when you see your child everyday, you don't notice gradual changes. She had no other signs of puberty etc. she's about the 40th percentile for weight and 60th for height.
Dr Google talks about possible cysts on ovaries and other scary sounding things. Given I am 9 mths pregnant I'm not sure I will be able to see a paed before bub comes and then who knows when I can get there after bub is born.

So I'm just wondering if anyone has any thoughts, comments etc?
