bibs while asleep

[Jellybean2010]

Is it okay to have a bib on a newborn while it is asleep? Ours likes to burp up / posset shortly before she starts waking up and can create a bit of a mess, so a bib might help. But are there any risks or downsides (eg could the bib choke or smother baby??). Any other helpful suggestions for our problem? Thanks in advance

They are a potential smothering/strangulation risk so better not to really.

I used to tuck a folded muslin under head (pulled tight and tucked into side of moses basket). As babies usually have their heads to one side hopefully it won't go on clothes and much easier to wash muslin that do full sheet change.
