Caught My Teenager Red-Handed

I found out last week that my teenager has been sneaking snacks into their room. I knew they were eating more than usual, but I didn't expect to find an entire bag of chips and some candy stashed away in a hidden compartment under the bed. Now, it's not like I'm shocked, teens need energy for all those late-night study sessions or whatever, but still, I wonder if there are healthier ways they could manage their snacking habits. So here’s my question to everyone: how do you handle sneaky snacking with your kids? Do you keep a close eye on it and make sure there are healthy alternatives around, or is it more of a free-for-all after dinner?
