Oh you poor loves, both of you . My dd was in HDU with bronchiolitis at exactly four weeks old, last Christmas (admitted on dd1's third birthday, and in over the holidays) and I will never forget how it felt.
Its just heartbreaking, and scary. She is so little, and you are only just post partum and full of hormones, and I do understand how it feels. I found talking to the other parents on the ward, and especially on the High Dependency Unit, helped me get through - that, and some of the staff, who were wonderful.
They kept telling me that at least RSV (if its an RSV Bronchiolitis, which most are) is predictable, and she will get better after the fifth day....one of them also said it would feel so slow it would be like watching paint dry, and they were right. I felt the beeping of the monitors was ingrained in my eardrums.
I'll be thinking of you and your little dd every day, wishing the virus gone and her all better. Take care of yourself as much as you can, xxx
