I've just taken DS for his 8 week jabs and as I went in the nurse says hello and then asks who I am as I am "obviously not mum"!
Admittedly I am an older mum (I'm 44) and my hair is a little grey as I have started having allergic reactions to hair dyes but she made me feel absolutely ancient 
AIBU to think that she was a little out of order here? Luckily I am not suffering from PND but if I had been feeling down I think this would have really upset me it did tbh
