If you have a new baby on the way, it is a great idea to have your bassinet attachment professionally cleaned and sanitised. The entire bassinet is pulled apart, and all the fabrics (including the mattress and frame) are submerged, scrubbed, flushed, and dried.  Once dry the fabrics are touched up, and the bassinet is re-assembled ready for your new baby to use, giving you the peace of mind that there are no nasty germs lingering from prior use.
