It will be one year of joint household by the time baby is born. Baby is very planned and loved. My DD doesn't like the idea of having a sibling in general but she's an only child so understandable. His DC are ok for the most part we all get along. I have a very close relationship with his DD ( so much that there's sometimes competition between her and my DD). His DS might be unhappy as he's the least "on board" about all being one family from time to time but things have settled. Do we tell them together? Separately? We know is has to be about the same time, ideally before I start showing.
