Sorry to hear about your DD. HOpe she gets better soon.
My tip is to do something special for them either for while they're in hospital or for when they get home.
I've written a dragon story involving my DS1, which I'm going to give him when his brother is in hospital, as we'll be away from him with DS2 for 2 weeks. DS2 is only 1, but as your DD is older, she might appreciate something special and homemade from you for while she's in hospital. YOu could read it to her in installments.
Also, you could try and focus on planning nice family things you can do together. Keep your mind busy with happy things, things that you could actually do when your family are back together. It's hard not to keep dwelling on bad stuff, but if you can push the awful thoughts out from your head for a short while, I alwasy think it gives your mind a break. This works for me. I'm convinced something terrible is going to happen to DS2 during his op in December, but I'm trying to focus on a family holiday and each night I try and go through what we'll do each day on our holiday and sometimes it does actually keep the nightmares at bay.
Hope this waffle makes sense. Hope your DD is OK. I'll be thinking of you. Keep us posted.
Pixie Blimey, have a hug (((())))) (don't do those much). I glad she's not in immediate danger now and hope there's much improvement very soon.
I don't know how you do it TBH. When dd has been in hospital I have to be there, I just fail to function otherwise. dh doesn't cope well at the hospital so it makes sense that we do it the other way around; I go, he stays here or follows on. Is dd still on her pump?
