I'm b/f my second child and they have just started nursery. I know that when I feed DS (and DD before that), I tend to feel tired and grumpy after feeding them. But today I was just pumping.. I felt great all morning then had to pump and got on with it. Since then though I've felt really tired and awful and down. I had lots of great plans for this afternoon, but now I just want to go to bed and hibernate! Anyone else had this?
