I always give DS (13 months) my shopping list when we get to the till during our weekly shop, as chewing on it keeps him occupied whilst I unload / pay/ pack. This morning a man ran up to us looking utterly panic-stricken 'she's got paper in her mouth, she's eating it!' I told him it was ok and he walked away. Glossing over the mistaken gender (I know it's hard to tell when they're so young), am I being stupid or is it ok? I regularly remove other stuff DS chooses to eat - worms, mud from the drain, the mouldy blueberry that hid from the broom - all of which seems to have done him no harm.
I'd have thought nothing of it but moments later a lady came up to me and said the same thing (but with the correct gender reference!).
What non food items do you let your DC eat?
