I only ever use bibs for feeding times now Alice is having solids.
I say you can't have too many muslins as I use them constantly! Under her chin when she was breastfeeding, or lately, bottlefeeding, wiping up dribble, wiping up when she's a bit sicky, wiping up when she wees on the changing mat, wiping up when the OH gets calpol everywhere but in her mouth, emergency bib, emergency t-towel (oops), when she was tiny we used to put one on the changing mat to stop her skin getting cold against the vinyl, playing peek-a-boo...
Every wash these days has at least a handful of muslins. They started out white and are now a range of shades from off-white to bright pink!!
