I thought that it hadn't worked, so I went back and named the baby again... except there were two! - Both of which have the same name! - It took me a while to realise what had happened - I guess I must have been given twins.
I had intended to have one girl, but in the confusion I must have made one of them a boy! - So now I have a teenaged boy named Laura. I'm sure he's gonna thank me for that

I'm also stuck with a useless baby that I don't really want.
And it means I can't get another sim for even more levels now than before. What happens if I delete the baby? - Will it free up a slot and allow me to have an extra adult now, or will it go back to the maximum for my level and give me another one when I normally would get one??
