A system for a vehicle child seat having at least a three-point harness, has a sensor 50 to detect when a strap 13,14,16 is loose/flaccid, to assist alerting a parent/carer that the harness is improperly fastened. The sensor can have a biased ring or sleeve 51, or an optical sensor, and apply a lateral force on a strap. The system provides an audible or visual warning (e.g. via Bluetooth), for example reducing radio speaker volume. The warning may be delayed allowing time to place a child in the seat. Presence of a child can be sensed using a weight or thermal sensor, and buckle coupling also sensed.
