I've felt the same on & off through this pregnancy. It was planned, but happened quite quickly and then I questioned whether it was the best 'plan' to make. I've got an almost 2yo & am dreading some aspects of having 2 in 2 years. But I remember it was a process of bonding with the first. And for all the stress caused (she has always been a really, really, really bad sleeper), I now can say whole-heartedly that even if I could go back, I wouldn't change a thing with her. I assume the same will happen with this one...

TBH, there will probably be days through the pregnancy, & then even after the bub is born, that you'll feel detached from them. But there will be more days when you love them. A lot of it has to do with how much energy you have - so take care of yourself & I think you'll find that the better you feel yourself, the better you'll feel in relation to the bub
