Well, I am just back from my friends house (again!) as I had something to hand into her, and it was just her hubby who was in.
He said that I should just have brought Beau along too as he will not settle tomorrow on his own as he has never been alone in the whole 10mths of his life.
I told him I had to give it one last shot, I will know by 1pm tomorrow, and I would always be wondering how it would have turned out if I brought him back tonight too.
We have only had Beau since the end of September, so if he has to go back, it will not be quite as heartwrenching as leaving Soph.
He is a lot more laid back than Sophie was, not as clingy at all, so you never know, but I am not getting my hopes up as I now know how horrible it feels when it goes wrong.
Thanks again to everyone who has posted, it has been a great comfort.
