How to deal with spouse gender disappointment..?

I’m currently 19 weeks, we won’t find out the gender until Valentine’s Day.

My partner is already confident that it’s a boy, which she’s so disappointed about..

How do you deal with this?

We’re doing a gender reveal and I don’t want her to break down if she sees blue.

Now, she’ll love our child regardless, but it hurts me the most to know she might feel depressed for quite awhile and it’s my fault that I couldn’t give her a daughter..
