when going on holiday i strap alsorts in the spare seatbelts so they cant more when travelling, but not the child car seat, im a little over protective and ensure my little one is properly strapped in, i was in a car accident when pregnant the first time sadly lost the baby the accident was an off duty police officers fault and was low speed, i got pregnant with my littleone afterwards and shes my world but im so aware of the damage accidents do as i still have back problems from my injuries, nearly 5 years on. with regards to the beer should be strapped in if not in the boot as will fly during heavy breaking and could be leathal.
