I wouldn't be of much help to you either I'm afraid! My first three kids are from a previous relationship, but my DH refers to all the kids his. I guess like Dee I don't understand your statement either.
But I do wish you all the very best & hope things work out, just remember to take everything as it comes, as anxiety can make things worse. Relax, I'm quite sure things will just fall into place when bubby comes!
