It's definitely a bit cheesy and American, but as my mum said "sounds suitable tacky" haha. It's just a bit of fun really for my parents, grandma (who is rarely in the UK) and siblings because everyone happens to be nearby at the moment. Also it'll by my partner's birthday, and the first time my siblings will have met him! So there's a lot of reason to make a cake and be a bit cheesy I think because these are the first grandchildren and great-grandchildren for grandma, they are quite excited. Any subsequent children might not stir as much excitement. Not that I'm planning on popping anymore out after this, I'd have to be mad to go through another first trimester! My mum said she said that with all 3 of us though.
