i bought some, but didnt really think i'd use them, but have used them loads.
i also have one in the nappy bag.
mopping up puke and spills.
protecting shoulders when burping.
protect their laps as bibs arent long enough
extra shade in the car window/pushchair.
damp muslin to cool baby in the summer.
lie baby on during tummy time to protect
baby and furniture/rug/duvet etc..
great giant hankies when they have colds.
quick removable extra sheet for under their
head in pram or bed when they are particularly sickly.
i'm sure there were other reasons too.
also they wash really well.
