Re: 8 week old frustrated at breast?
This is quite possible. If your supply has regulated itself and the OALD has subsided, your baby may be fussing because he's used to the fast flow and would like to have it back!
Oh, I did have an oversupply/overactive letdown early on. Perhaps he got used to it?
I know it's tough to not give a bottle when you run into extreme fussiness, but if you can tough it out you may be rewarded. You don't want to get into a situation where your baby realizes "Hey, the sooner I throw a fuss, the sooner I get a nice easy bottle!" and starts rejecting the breast.
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!"
