I'm so incredibly sorry to hear about your beautiful daughter. Our son was still born in February and it truly is such an awful thing to go through.
I'm so glad your son and daughter are together, I'm sure it's very comforting.
We have a private thread for mums of stillborns and would love for you to join us. It's nice to have a private place to talk.
Feel free to pm or chat here.
