Re: can he he addicted to nursing? mentally? physically?
OMG, I can just imagine the big puppy-dog eyes welling over with tears, and the trembling lower lip as he says "Oh, you're making me soooo saaaaadddd...." Kids are so ingenious when it comes to getting their parents to do what they want!
I am that this is not an addiction issue, but a limits issue. I think the advice to get out of the house more is really excellent. I also want to suggest using a kitchen timer, and doing things like saying "You can nurse in 5 minutes" (to start, and then move it to 10, 20, 30, etc.), "as soon as the clock goes beep-beep-beep." Kids often get a real charge out of watching the clock and then notifying you when time has elapsed. And just getting your LO in the habit of waiting a few minutes before nursing could be the first step to going longer stretches between nursing sessions.
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!"
