We have just bought a Citroen C4 Grand Picasso, which we're very pleased with. We allowed my granddaughter to sit in the front passenger seat. She is now tall enough not to need a booster set. A friend has said to me that this could be dangerous until the child is adult size, as the airbag could suffocate her if it was activated during an accident. Would we be better de-activating the airbag when she travels in the front seat? Or do you not advise having older children in the front seat until they are a certain height and weight? We would be grateful for your views.
