I have been married to my husband for 3 years now, I have one son from a previous marriage (he will be 10 in Jan.), and am pregnant with a girl (due in Dec.). Custody is mainly mine, but we've went back and forth from time to time so I assume now that my ex has been staying in state for awhile we may adjust again. We usually get along now (though the first year or two were rough), and try and discuss and compromise on these things.
My current husband finds being a step parent hard sometimes, and I can see where he is coming from. Also, he has never had a step-parent where as I had two so the concept isn't new. I always just looked at them as additional parents and still do. I try and be supportive of my husband, but also realize that sometimes I step in and/or contradict without meaning to and it is something I am working on. I think I was just use to being the sole parent for so many years that I do it by default sometimes. Thankfully it doesn't happen often and I usually find a way to make up for it (my son is pretty mature so I will simply say: you know P and I have talked about this and considered trying this ... etc.).
On the flip side sometimes I feel like it is hard b/c we have different parenting ideas, I have to juggle parenting decisions between ex husband, current husband and me (not simple normal every day things but big issues etc.) and I am that person that is in the middle.
My son and husband get along great and in some ways he is closer to my husband b/c he's been there day in and out. However, ex husband has being doing well the last year and a half so we shall see. I encourage him to have a good relationship with both.
I am nervous and excited about baby girl, but do worry about my son's adjustment to it. He is afraid he will be left out so I am going to have to make sure I have special time with him (he has a few extra curricular activities so I'll keep taking him to those), and find a way to blend in family time with all four of us.
Sorry for such a long intro....
