But she's a girl!

Why is it that we now live in a world where if a baby girl has something on that is blue she is considered a boy or even a little boy having something yellow.  I am so tired of people just assuming because my daughter has a navy blue care seat with rainbow colored animals on that she is a boy. 

When my daughter was 2 months old I was in a store and some woman looked at my daughter and asked me how old my son was.  I told her 8 because that is how old he is.  Now if she asked me about how old my children were I would have told her my son is 8 and my daughter is 2 months old.  After she finished scolding me for my smart mouth (this also included finger waggling) she informed me at her age it does not really make a difference if she is a boy or girl.  This lady (term does not really apply to her) had the nerve to get offended when I reminded her that seeing as she looked to be in her 70s that the old people diapers are not located by the baby diapers.  After all, at her age it does not really matter right?

Then at my sons 2nd grade school parent teacher meeting his teacher made the remark about how nice it must be for him to have a baby brother!  I had her dressed in a teal green sweatshirt with a heart on it and a matching bow in her hair.  My son being of few words just rolled his eyes at her and said "duh that's my sister." Thus ensuing pissing off his teacher and her telling me I should really should teach my children that it is not appropriate to smart off to adults.  Thus ensuing kicking my mouth into protective mommy mode and telling her about the little phrase you can use to remember what the word assume means.

My daughter looks like a baby.  I know its hard to tell gender sometimes.  If your not sure wouldn't it be easier to just say what a cute/adorable baby, or perhaps ask the babies name or age.  Usually the parent will say she/he is ....
