Decisions

So I have an ultrasound on the 10th @18w and I have the option to find out gender again. I had the option @13 weeks but I declined. Everyone wants to know what I’m having but truthfully this is my 3rd and I don’t want to know until birth. I know they make gender neutral things and that’s what I plan on buying. Question is do I just find out, or hold my ground? If I choose to hold my ground, what do I say?
