Snacks?

How often are you offering your LO’s snacks? Mine eats lunch and dinner pretty well and drinks milk in the morning and before bed. She eats breakfast sometimes but typically isn’t that into it. I was giving her milk after her afternoon nap but she doesn’t always drink it. I don’t offer her snacks a ton but when I do she’s always willing to eat them... but it doesn’t seem like she’s starving if I don’t give her a snack. I’m just trying to establish good eating habits but not sure if I should be offering snacks daily or multiple times a day or what!
