Hi,
I'm sorry you are going through this but I hope it helps to know that I also went through the same with my DD who was 23mth old at the time of my DD2 birth. I had bad morning sickness as well as SPD and was on crutches due to this. My DD wanted nothing to do with me and everything was Daddy Daddy. It was hard to see but also nice to observe the bonding developing between them. Although rest assured soon after I have birth and was walking around again my DD was mummy's girl again! Until then big hugs for you.
