So me and my partner have a daughter who is almost one and are due another baby in November. Me and OH weren't fussed about the baby's sex at all but found our we're expecting a baby boy. We've had lovely reactions off everybody except MIL who keeps rubbing me up the wrong way with the sort of comments she is making.
I should add that my partner is her only child and she is the typical overbearing, pandering to OH type of MIL.
So firstly she said something to the effect of "ooh I can finally have trainsets again!" the first time I just thought it was a bit weird but upon the 3rd time of her saying it my partner replied "daughter would have trainsets too!" And she said "yes but it's different" 
Another time visiting our house she saw some clothes hanging up that we had bought for baby. She said "It's lovely to see little boys clothes!" Which doesn't seem too bizarre but she basically gave me a dressing down about our daughters wardrobe and how "she has too many clothes". She also put on Facebook "how wonderful it will be to have a mini-partners name"
I'm starting to feel like there is going to be favouritism especially when the baby is born and also wish she would acknowledge the baby will be his own self. AIBU to get annoyed? I don't mind her being excited but it already feels like my daughter isn't good enough.
