Jas - you're doing an amazing job . If it's any consolation, I had those patches - boy, did I have those patches - and I used to come in here & post and it would help get me through. I had one time (when DH did his back) and I just thought about NOTHING but stopping pumping. In retrospect I'm really glad I pushed through it.
What are you doing while you pump? Can you try do some things that are really "you" time (as much as possible anyway!). You said you're waiting until it's time to express, can you express a little earlier then go to bed? Sometimes I think that feeling tells you that it's time to tweak your schedule a bit... Also, what are your goals? I think it helps to focus on the next short-term goal (well that's what the wise ladies on here suggested ) and I found that was helpful.

Emmykate82 - will she take a dream feed? Otherwise, I agree, if they don't want to feed, then they don't want to! Very difficult to force that. I'm sorry to hear about your mum, that sounds so frustrating. I had my MIL, FIL & a paed all telling me to wean at one stage, and it was so annoying. Just remember, your body, your baby, YOUR MILK! Besides, what if you stopped expressing, gave her nothing but formula and the situation worsened? As for the defrosted freezer.... ooooh if that was me I'd be bawling. That's a horrible thing to have happen and I agree with Jasp, you are coping with everything SO well!!!
