I have two dss's, 7 and 5 years. There bm died from cancer in august 2009. I started seeing my dp about 6 months after her death. I was slowly introduced into my dss's lives. We all get on very well and they're happy to have me around all the time and treat me as an equal to daddy. I think we have a healthy attitude towards their bm. They both have a picture album which we sometimes look at together. They will always know who she is. Me and dp got in engaged last year and the wedding is set for this July. My dss's are very happy. My problem is that my dss's have said on several different occasions 'when you marry daddy you'll be our mummy'. We have said we will discuss what they call me when we're married. At the mo they call me by first name, often with a 'my' or 'lovely' before my name. Me and dp don't really have a problem with them calling me mummy but don't want to seem disrespectful to their bm.
What do you think?
