Stealing the spotlight?

Lauren
Hey all,
I need to get this off my chest....
My husband and I were trying to get pregnant for 6 months to get pregnant before it actually happened and we are BEYOND excited for our 2nd baby.
My husbands brother and his girlfriend had supposedly been trying also (but kept it a secret) and got pregnant 2 months before us with their first child. Now, after they found out we are also pregnant they pretending like they were so happy for us and how our babies will be so close yada yada yada...
We're finding out that they are going around town telling people how we "stole their spotlight" because they were TTC before us...?
Now, anytime we talk about our baby, it's like we're doing something wrong?
He went as far as to NOT EVEN INVITE his own brother to their gender reveal party...
I'm beyond shocked. I've NEVER heard of this...
Any suggestions? Thanks all
By the way... I'm not gonna stop being excited about baby number 2 just to spare his punk brothers feelings... 
Here's a pic of my 13 week belly and our ultrasound... 😁
