A little background. I've been married to DH a little over a year, together for 3. SD is 6 and she has lived primarily with us for the last year. Before that she lived with us 50% of the time, on 2 days, off 2 days, on 3 days. That sort of thing. 

Anyway, for the most part we are close. I do love her but sometimes she does annoy me and I like to have my own space. 

Lately, I've been wondering if we should have our own baby. This would be my first baby, DH's second. SD has a half sister (3) at BM. Plus a step-brother (8) at BM's that she only sees in the summer.
