Recover things and give it later 🤷🏼♀️
"Ok, I'll put this back in the fridge for next time." and slowly put it back in the fridge. 7/10 times they will run back and grab it from you. For the other 3, just put it back and offer it at the next snack time. If they don't eat it by the end of the day, it's yours. 😀
I would just save the snack for later that day or the next day 🤷♀️
I would put it back in the fridge.
Maybe try offering a drink instead of snack.. my son use to do this and in all honesty was calling it hungry but really he was just thirsty. Otherwise I agree with other comments of offer said opened snack later.
You offer it again in a few minutes and then you move from there lol it’s gonna keep happening
