Re: 11 week old refusing to nurse in the evenings...
Does your milk come out right away? I had problems with my youngest because you actually have to suck for a minute to get my milk started, and he didn't want to take the time to do that. I had to pump to start it and then he would nurse no problem. I don't remember how long that lasted, but I know it wasn't too long.
I sure hope you have better luck soon. I know how frustrating it can be. Here's a couple for you!
