Just need some advice/tips

Iz

My LO is really suffering from a cold.. we've done the usual, nasal spray, vapour plug in, tried (and failed) with the aspirator thingy but, she's up every 15 minutes struggling to breathe. I've propped her up using a bit of material under the mattress but, again she's still snuffling and waking tearful due to not being able to breathe. I feel helpless is there any other tips or advice Mummies or Daddies can give me. Thanks in advance 😘
