How to keep mum from my scan??

[AnyDream]

Tell you mum they are going to have to do a Transvaginal scan and you wouldn't feel comfortable having her there (!) Well it's a pretty spectacular fib or you could just be honest and say, "Mum, we don't want anyone else knowing the gender, it's our special surprise" and if she is offended bad luck. She'll forget it soon enough once she's holding grandbaby in her arms!
