"Tuck in" is a phrase used in informal English when you are going to start eating a meal. You can say it to someone else as an invitation to start eating, or say it yourself to show that you're about to start eating. It means to begin eating your food, typically by putting your napkin in your lap, picking up your cutlery, and starting to take bites of your food. You can also use "tuck in" when you are putting someone or something to bed or when you are adjusting clothing or blankets to keep someone warm and comfortable.
