To be honest I think you need to sit down and have a chat to DH and try and get him to say something - she is his mum. SOmething like, thanks so much for your advice, mum, but that's not the way we do things.

If that doesn't work, I'd suggest you chat to her and say that although you appreciate that's the way she does things and it has worked for her, you feel differently.

Remind her that it's your bub and you are so excited. Maybe say you can't wait to choose everything for the bub and how great it is a mummy can make choices like these
