I'm going to make a sweeping generalisation here, but most new mums I know are not ready to let their new little person out of their sight. Hell it's traumatic leaving them to go for a wee. We check them every two minutes to make sure they are still breathing. There's no way on this earth that you are taking my new-born baby out into the big wide world and away from me.
A chatterbox is quite happy to talk to anyone about anything. And by anyone I mean; strangers in the street, the ladies in the supermarket and the neighbour you don't know very well. And by anything I mean; what picture they have on their pants today, that Daddy parped really loud this morning, and that "Mummy said our neighbours are very noisy."
