Re: 2 month old not rooting anymore? Normal?
Very normal for instinctual hunger cues like rooting and mouthing to vanish as time goes on. I think it's a feature of baby's increasing ability to communicate her needs via crying- now that she has discovered the most reliable way to say "feed me!", she doesn't need to bother with the subtler cues.
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!"
