It is very difficult to start afresh when you are an already made family isnt it. I can understand why you are feeling anxious....I think its completely natural and to want no distinctions as to whose baby is whose is a perfectly reasonable request.

My first two dd's are from a previous relationship but having been with my Dh since they were 18 months and 31/2 I think we missed any serious probs because they were so young and my DH has been Dad to them ever since. There are NO and I mean NO distinctions as to who my DH has biologically fathered and who he hasnt and quite frankly I wouldnt put up with it if there was. Maybe you need to reiterate that your Dh has married into a family already and that its the package deal or nothing..that separate titles or whatever is only adding to your stress and making you worry unnecessarily and that is not good for the baby either.

I have seen blended families work so well and others not work so well...i hope you can smooth out any wrinkles you may have and enjoy the rest of your pregancy and beautiful new baby.
