What's up with this is that your LO is a baby, and every time you get used to something, she's going to change EVERYTHING.
In case you're concerned, there's nothing wrong with "snacking". It gets a bad rep from people who claim that babies should eat "meals" and not "snack"- but their assumptions about what babies "should" be doing are based on the behavior of formula-fed infants. Small, frequent meals (a.k.a. snacks) are the norm for breastfed babies, because breastmilk digests quickly and completely, and because infant tummies are tiny.
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
Coolest thing my little girl sang recently: "I love dat one-two pupples!"
