I agree with Cookie, £100 is nothing for what happened and the angst is has caused you, aside from the financial cost to you. Its natural to think things over after the initial shock has worn off. I don't know the answer to why the airbag didn't go off, I would have thought it should if you braked hard. If you'd had Jackson in the car, I know you'd have made sure he was perfectly safely strapped in, so as safe as he could be and he'd have been fine. You can only do so much to stop something like that happening, beyond that, you're worrying yourself needlessly. I know for us to say relax, its easier said than done but try to distract yourself with some rubbish tv or a good book or something before you try sleeping, so your mind is off it. Or just fall asleep looking at that photograph
Your weekend sounds perfect, hair appt then baby snuggles
