...without seeming to show snatching as acceptable?
dd - 16mo - particularly likes to run around with things like toothbrushes in her mouth, ie not great idea. occasionally, i have snatched or prised from things from her hand (only in time emergency or safety concern) but obviously that's not great role modelling, so just after any tips.
I'm with the insider. If you need to take something away from them, it's either because it's dangerous(toothbrush in mouth, something small they can swallow), something precious or breakable of yours , or a toy they've snatched from another kid. If they don't give it back when asked and if distraction doesn't work then a bit of force is sometimes necessary and it's not called snatching when you do it
