So I haven't driven anywhere with her on my own yet there's always someone in the back seat with her or I'm in the back seat and DH drives she is 12 weeks now , I'm very nervous of her stopping breathing in the car seat , I've no reason just neurotic first time mom who's done all the reading about if they go chin to chest in car seat and the risk of asphyxiation, my worry is the handle on the car seat obviously has to be left up for safety reasons as it acts as a roll bar in the case of an accident but then it blocks me seeing her in the mirror I have facing her , I have no choice but to do a 30-40 minute drive with her on my own next week is there anything else I can do ?
