Megsmum, I'm so sorry to hear about your loss. Although I haven't experienced this myself, I wanted to post a reponse here so that you would know that I'm thinking of you. I'm sure others will contribute more useful advice but this is what I can suggest:
a) Give yourself time to grief - acknowledge that you have suffered a loss and recognise that for the next month things are going to be tough. Put a time frame on it initially and know that most people are able to overcome trauma in 1 month (not that you still won't grieve but it won't be the same as the intial trauma reaction).
b)Don't put on a happy face when you don't absolutely have to. That might mean arrange someone to look after your DD for a while so you can have some time alone. That might mean crying alone when you need to.
c) Allow your hubby to grieve in his own way but communicate to him how he can best support you. "I really need cuddles etc right now".
d) When you are ready, turn your thoughts to how you would like to remeber your angel be it dedicating a new plant in your garden, a poem or a special piece of jewellery.
e) Remember previous times in your life when you've faced similar tradegies and think about how you overcame them (you did overcome them becuase you are strong!).

My prayers are with you..
