My husband and I do not want to know the gender before birth. My mom is unhappy.

Hey guys,

I have a dilemma. So me and my husband both want our baby's gender to be a surprise. I know it may sound weird but we both think it will be such a happy surprise after birth.

On the other hand, my mom is super pissed about it. She thinks it is ridiculous and it makes planning alot harder. My husband and I are into neutral colors and have theme ideas that are gender neutral as well. I can understand that she just wants to get items that will be a specific color, or cute clothing etc, but we just want to wait. Is it wrong that we both want to have it be a surprise. I hate feeling like I'm guilt tripped into not wanting to do what my husband and I want to do. I could also understand stand if this was her first grandchild but my birth had two. Any advice on the matter❤
