Anxiety arguments!

[Ohmymama]

Out for a drive and we pull over for a snack. I open the boot and sit in there with my 3yo. My husband shouts at me for showing our 3yo how to get into the boot. He worries that our 3yo will climb into a random boot and get trapped. Reasonable?
Have you ever resolved arguments over anxious thoughts?

Why on earth would your 3 year old ever be unattended long enough to climb into a random boot without you seeing him? I think he is overreacting a wee bit there.

Thank you for the reply thesnapandfartisinfallible.
He just thinks 3yo is that fast you might not notice. Hears stories of kids running away as soon as your back is turned.
