MM:Baby?

[Butterscotch]

So, my baby should be born soon (I'm assuming it takes two months to be born, like in most HM games)

What will it's gender be? I've heard conflicting reports:
a)the baby doesn't have a gender, whatever name you give it is it's gender
b)it's a boy
c)the gender depends on the color of the blanket (blue for boy, pink for girl)

The guide book apparantly refers to your baby as him/her and he/she, which would support the first and last one.

Does it's appearance change depending on:
a) your gender
b) your spouse?
c) doesn't matter
By which I mean, does the boy's baby look different from the girl's baby, but is always the same no matter who you marry; or does it vary depending on who you marry? (Blue's baby would look differet than Alex's baby). Given the number of potential spouses, this seems unlikely.
Or is it simply just one baby, and it doesn't matter if you're a boy or a girl, or who you marry, no matter what it's always the same?

This is a long post, and possibly confusing. ^^;
I'll be glad to clear things up, if any of this is unclear.
