To not want to have to skirt around my own baby's sex?!

[022828MAN]

DH and I found out the sex of our baby 4 weeks ago. We hadn't really spoken to MIL or FIL since, but yesterday MIL popped round and had a catch up in our garden. She asked how the 20 week scan went and just as I was about to say yes all is looking well and the sonographer said he looked healthy, she said 'oh I don't want to know the sex though'. So I then spent the next 20 mins talking about 'it or them' when DH and I (and me and my friends and my DM) have been referring to him as he.
When she left to dh I said if I see her again I'm not going to go out of my way to not say he as it just felt weird and like I am being made to jump through hoops for something I don't really see is her decision to make really.
WIBU to just say the next time she or FIL asks 'yes he's been kicking lots...' or something similar?
Fully prepared to be told I'm BU but MIL has form for controlling behaviour and I just feel like this is another way of making me feel uncomfortable just talking about something naturally which actually has nothing to do with her?

TBH I would put it in the public domain. I am not really into all that social media gender reveal crap but I'd put it on facebook (or any platform or whatsapp group she's on) and tell the rest of the family.

Again, there's no need to be cruel about it.

Where did OP say she was going to be cruel or mean about it?

Why are some posters expecting OP to just yell it in her face or something? Give OP some credit. She came here asking for advice. If she was going to be “mean” about it, she would have already told her.

SO weird! She has no right to control you like that when it comes to your own baby. Stop pandering to her right now or she'll get much worse when it comes to breastfeeding/potty training/weaning/having newborn over night with her for a week....

Ugh I had the exact same thing when I was pregnant. My fiancé begged me not to let slip so I tried really hard but I did say "he" a few times by mistake. It was quite annoying really. My whole family knew but none of his did and it was stressful not to say anything.

Just do what you want, it's crazy to be ruled by them when it's your baby. I wish I'd just bloody said it.

I’d alternate between he & she Just to mess with her ... next time she asks “she has been kicking a lot” then next time “he’s ....”
If you slip up it won’t matter but if you think before you say change it to she & wait for MIL to be confused!

this happened to me too. BIL said he didn't want to know the sex, and I really didn't want to have to think about not telling him, so I just posted it on FB for all to see.
