I wasn't sure where to put this (couldn't find an appropriate place in the 'Being a parent' section). I just wanted to ask whether it's reasonable or not to leave a baby in the car when you buy petrol. My DH and friends say "Yes, of course" and so I do leave my DS in the car usually but today I was at a large Supermarket garage, in a long queue and felt really quite stressed as it seemed as though I was really far away from my car. My DM says "Well, what could happen to him?" and I do see what she means but it just feels a bit odd (he's 5 months). There are a few other situations where I'm also not sure such as leaving him in his bouncy chair in the garden or leaving him in the car while I go back in to get something from upstairs. I'm guessing I'm being ridiculously paranoid but just wanted to know what other people consider to be reasonable.
