Re: Biting
First of all, a big
to you! Biting is no fun!
The way to handle this is the same as you did at 5 months: when she bites, immediately take her off the breast, say "No biting, hurts mama!" or something similar, put her down, and walk away. It may take multiple repetitions for yur LO to figure out that biting always results in the end of fun nursing time, but she will eventually realize that nipping you is totally counterproductive.
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!"
