Vent about family member being negative

Brandi
Sorry just need to vent! We are currently ttc number 2. Our daughter just turned five and wants a baby sibling so bad and so do we. I recently shared with my mom we are ttc. She is so negative and says we don't need another since we have one perfect healthy one. It makes me so mad. She keeps making comments about how we don't need anymore. We both have very well paying jobs, own a home, cars and more. We are. Very financially stable. It's just pisses me off and really is nobody's business I just get tired of the comments!
