Thank you all for the wonderful advice! Still feeling teary (you're right Meg - I think it's the baby blues hitting me at the moment) but now a little more under control. Think I would have jumped off a bridge by now if I didn't have such a loving and supportative husband.

She's been sleeping on my chest for the past hour & a half; occasionally making little noises and stirring; but mostly asleep. For the most part, I gaze at her and just melt. It's just those insane moments (mostly at night when I'm wide awake with a restless, crying baby who is ripping at my nipples for four hours straight and DH has fallen asleep) when I feel almost resentful to her when I hear her begin to stir when she's fed for over an hour and only slept for 15mins.

Jules, I do have the Avent one. The seal doesn't seem to be functioning too well but I'll take your advice and give it a rinse again and assemble it whilst wet.

I'm tired and frustrated; so much of this comes from conflicting advice (especially from midwives etc) about what is acceptable for babies of this age. I mean, she's only a week old and I'm falling apart. It seems like every second resource tells you that dummies, expressing milk and feeding via bottles whilst still BFing etc are only suitable from 6wks onwards. What the heck do they expect you to do until then?
