Oh bramble hun I'm so so sorry to hear the sad news about Poppy. Please accept me sincere condolences. I know this must be breaking your heart at the moment and I realise there are no words that will be able to comfort you but you must take comfort from the fact that Poppy knew how much she was loved and she was a happy little girl.
I realise this is not the outcome you would wish have wished for but at least you were able to bring your little girl home and this will help you to be able to get some sort of closure over time ... there is nothing worse than "not knowing".
My heart goes out to you are this terrible time and please remember we are all here for you if you need to talk.
RIP Poppy darling ... play hard at the bridge xxx
