Have you got some sort of vapour rub for her chest to help with the snuffling. Also rubbing the vapour rub on her feet will help too. Eukybear is a good one, not sure if you will get that in VN???
Or a room vapouriser?
Top up the baby panadol if she is throwing it up.
Give her extra bottles if she will take them to keep up her fluid intake.
You could try saline drops to help her sneeze out the goo.
Give Poppy a big hug and you need one too
